Fetal Development

because women with regular periods would not be ovulating yet therefore there would be no egg for the sperm to fertilize

a hot bath can indeed seriously affect a developing baby.

An increase in the temperature will in turn heat the fluid in the amniotic sac thus affecting the baby. And while you can sweat out the excess heat, your baby cannot. The temperature of the water will automatically raise the core temperature of your body causing dehydration and overheating. Not only will this extra heat damage the developing cells of the baby but it will also prevent the oxygen from reaching the embryo. Along with that it will increase the heart rate and reduce the blood flow to the fetus thus stressing out the baby. The serious threat of this is that it might lead to malformations or birth defects in the baby and could also bring about miscarriages.

No. A man's sperm carries exactly half of the DNA required to fertilize an ovium (woman's egg). It contains nothing more. Neither the sperm nor the ovium are capable of life without the other half of the DNA. When the halves of the DNA combine then there is enough to 'program' the cells to begin division/multiplication, which might result in a new being. This is true of all mammals, not just humans. The DNA combines so that the new entire whole is not exactly like either of the halves. So the sperm's DNA does influence the blood type of the child but there is nothing of the father except 1/2 of his DNA. Same is true for the mother.

Yes, there are blood test that they can do to check for different birth defects, including down syndrome. If your dr hasn't done that yet, and you are concerned, you may want to talk to him/her about it.

Yes, that is a very normal heartbeat for a fetus. I have had 3 children & pregnant with my 4th & my 1st 3 kids heartbeats were in the 160's. All girls. This baby though I am pregnant with is ranging 140's to 150's. Your baby has a good strong heartbeat. Good Luck!

A normal heart rate for a fetus is 120-160.

At my first ultrasound I was 10 weeks 5 days and my babies heart beat was 176...it slows down throughout pregnancy.

There may be a problem. If the baby has kicked before and has now stopped you need to see a midwife or ob/gyn. If the baby has not yet kicked you may be a little out with your dates. With your first baby you don;t generally feel it kick until 20 weeks. And if you are overweight it may be later than that.

There is a possibility she will have a big baby. I wouldn't worry about it too much. I bet another ultrasound has been booked that will be fine. I was induced at 36 weeks becasue Twin 2 wasn't growing. Twin 1 weighed 4lb 15ounces, Twin 2 weighed 6 lb 3ounces!!

How far along you are based on your LMP is called Gestational Age. Technically, in this method, for the first two weeks of your pregnancy, you aren't technically pregnant. What you found out at your sonogram was called Fetal Age, this is the actual age of your baby since conception. Conception usually happens two weeks after the first day of your last menstrual period so your sound like you are right on track. I am 7 weeks and 6 days pregnant according to my gestational age, and 5 weeks and 6 days pregnant according to fetal age.

i need help for about the midicine i take coz i have a infection womb uti

Depends on how long gone it is. It covers everything from a hard-to-spot little lump to a readily recognizable baby and everything inbetween.

to check on a baby while you are out of the room

Well the most obvious answer, you could take a test. But to try to help you out a little more, your symptoms of pregnancy will usually appear anywhere from the first week of your expected period to 1-2 weeks after your first week of expected period. Your first signs of pregnancy most commonly include missed period, tender/swollen breasts, change in color of the breasts, fatigue, nausea/vomiting, increased sense of smell, and weight gain.

No, they are safe.

go to www.webmd.com It is difficult to tell without seeing it. However, it could mean you ahd a small "bleed" that could either resolve itself and cause not problems, or it could potentially cause you to have a miscarriage. You need to discuss this with your doctor.

Yes they do get rid of waste products when they are in there webs.

My best friend just had her baby at 30 weeks and he came out 3lbs 2oz and is doing very well. Your baby might have to stay in the NICU for awhile though

Good luck!

'Before birth' a fetus could either be a boy or a girl (I'm just going to assume you mean before the woman goes into labour) The expression of the fetus' sex occurs around six weeks after conception. Before gonad differentiation the fetus has no sex (no testis or ovaries at this stage, so 'no sex'). After gonad differentiation it will either be a boy (testis) or a girl (ovaries).

To be more specific, every fetus starts out in a feminine direction unless several genes on the Y chromosome exist and trigger sex-differentiation in the other direction. So by "default," everyone would end up a girl if it were not for certain proteins on the Y chromosome (or technically even an X if it had these genes instead of the corresponding ones which usually exist there).

There are some males which are conceived missing the receptors for male hormones. So despite the sex-differentiation cascade, the fetus would develop outwardly as female, since although the Y-chromosome causes the adrenals to produce DHT to trigger the male differentiation, the body cannot use the DHT, and the male structures never completely form. Because of that, there are no inhibitors released to stop the development of female genitalia. But because the genes for female gonads does not exist, such girls end up with shallow vaginae, undescended testes (which are of no use to the body since they lack male hormone receptors to use testosterone), and delayed puberty. They do have female puberty because unused male hormones converts to estrogen in the body. That is something that steroid users learn the hard way, when they end up with feminine breasts in addition to muscles. They grow taller than other girls because the estrogen comes late. Usually, such girls are well-adjusted into the female role, and they may be given hormones and surgeries to make their features more typical for women.

I just went in for my ultra sound this morning. I am 8 weeks and 2 days and the heartbeat was 177 my doctor said that it was normal.

Yes it is normal to feel your baby move under your belly button I'm pregnant with my third child and you feel the baby move any where it feels like kicking or turning. The only time you need to worry is if your baby inst moving at all.

Until he realizes he has a mental disorder and believes he nees help, he will not change. He will not think he is treating you bad. He will believe that you treated him bad and "weren't there for him." He will castigate and malign you to those you mutually know. He may seek you out again as a source of emotional/sexual supply or he will decide to be with another person who will provide what you did or give him even more attention and regard. If he feels he can replace you, he will. Narcissists are emotional vampires--they feed off of the feelings of others and give nothing in return. The only way you could stay in a long term relationship with one is by submlimating your own feelings, needs and desires, and going along with everything the narcissist wants. Again, this only works as long as the narcissist wants it to--if he bores of you or finds a "better" person to supply his needs, he will abandon you. Does this sound like a relationship you want to get back into?

Hello, Blood can be difficult to see on a ultrasound. Picture a ultrasound picture, the images are grey and hazy. Also if you are 4 weeks pregnant the pregnancy would not be visible on a ultrasound scan until you were 6 weeks pregnant. The only person who can accurately and thoroughly read a ultrasound is a Radiographer or a Obstetrician Doctor. I would make a appointment with your Doctor, have a pregnancy blood test performed and book a ultrasound scan for 2-3 weeks time. You need a quantitative beta HCG blood test to measure the level of HCG in your blood which will also tell you if your pregnancy is viable. Good luck.

during routine prenatal visits a Doctor will measure you uterus in centimeters, your centimeters should equal gestational age. IE. 26 cm 26 weeks

A 3 month old embryo is a fetus in the womb but after 3 months of birth it is a baby.

A teratogen is an agent or factor that causes malformation of an embryo. It would be likely to result in a spontaneous abortion, another name for a miscarriage or loss of the unborn child.
