Checkups and Tests During Pregnancy

A "little baby test tube" is not a standard or recognized term. It may refer to a test tube used in a laboratory setting to hold small volumes of liquid, or it could be a colloquial or humorous way to refer to a test tube baby, a child conceived through in vitro fertilization.

You need to go to the doctor's office or you could have irregular periods that's all i can think of

Usually around two weeks, sometimes sooner.

yes

Depends, if you are sexually active you could be pregnant. From what I have read this is most likely implantation bleeding. I would buy a pregnancy test :)

Most paternity tests are based on comparisons of DNA. DNA evidence can only exclude suspects. DNA sequencing is used because there are so many different sequences you could have at any one place, the odds of any 2 people, except identical twins, having the same DNA is nearly impossible. However, if people are very closely related (like father-son), they will share a number of common sequences on a DNA test. We'll say 5 out of 10. Though it's usually VERY unlikely, 2 completely unrelated people can still share sequences in certain places. This is why it can only legally disprove paternity cases. If 2 people shared no sequences, they couldn't be related. That's not to say, however, that 2 people who share a number of similarities are related.

You need to see your doctor as soon as possible for a through evaluation. Pregnancy is a possibility.

I don't think amniocentesis would be done at 7 months. Wait until the baby is born. Amniocentesis is where they take a little of the fluid from your sac and test the DNA for anything from genetics to disease. It is not completely safe, a doctor would recommend you wait until you have the baby before determining paternity. There is always a risk with amniocentesis.

I think you should read the website details I have attached to this answer. The treatment prescribed to you is exactly the treatment I had during my pregnancy with my little girl. I had 2 miscarriages prior to successfully carrying her. She is healthy and fine. However, I recently got pregnant again and my doctor put me on the same treatment and I miscarried.
