Yes
Almost any woman who has periods can get pregnant (assuming they have unprotected sex).
yes, you can get pregnant on the first day of your period. there really isn't anything you can do about unprotected sex. maybe the day after pill? but it properly wont work if your already pregnant.
If a woman does not have a period she cannot get pregnant.
Yes a woman that is pregnant will stop having her period, until the baby is born.
No, the type , length or anything else with underwear cause her to get pregnant. A man and a woman having intercourse is needed for a woman to get pregnant.
A woman can only become pregnant if sex was done unprotected, or if a condom broke during protected sex. if your a virgin, you cant be pregnant.
not necessarily
Prenatal tablets are vitamins etc so a very big risk since you are unprotected.
If you had unprotected sex 2-3 weeks prior, it could very well be implantation bleeding/spotting. 20-30% of woman experience this. SOME will actually confuse this accurance as their period.
No. A woman gets pregnant by having sexual intercourse with a man ... or by artificial insemination.
What you have described could be more succinctly called female infertility. It means that a woman is not able to have babies.
Yes, if the sex is unprotected sex, by which we mean that contraceptives such as condoms or the pill etc are not used. If it is unprotected sex then a woman can get pregnant from the very first time she has sex. If protection has been used properly in all cases of intercourse then the chances of pregnancy are highly unlikely, although there can be exceptions. For example condoms are 98% effective so for every 100 women that use them there is a chance 2 will become pregnant.
