They take a blood test so they can see what your hcg levels are. Your levels get higher the farther along you are. A blood test can determine pregnancy alot sooner than a urine test and is also more accurate.

A blood test can detect pregnancy earlier than a urine test, usually around 6-8 days after ovulation. It measures the levels of human chorionic gonadotropin (hCG) hormone in the blood, which is produced by the placenta during pregnancy. This test provides a more accurate result compared to a urine test, especially in cases of early pregnancy or when complications are suspected.

What should you do if a blood test says you are not pregnant but you have not had a period for months?

I'm confused as to how you had a blood test for pregnancy, but didn't see your doctor. Surely if you saw your doctor you would have asked them what you should do next and what is causing your periods to be absent. Go back to your doctor and have them run tests to determine what's wrong.

I have had 4 inseminations and still am not pregnant. My doctor tells me that pregnancy symptoms will be the same as anyone else's pregnancy symptoms.

If you didn't have a period for 2 months and had neg hpt's yet still had pregnancy symptom then had a period could you still be pregnant?

Yes you can still be pregnant after you have a period. It is not common and not always healthy for the baby that you're losing blood, but it is possible. Just ask my sister. She had normal periods all throughout her pregnancy with my nephew. Again I say it is not common for this to happen, but it is possible. Take a pregnancy test to determine whether you are or not. If you do not trust the store take-home type, then go to your doctor and get a blood test done to determine if you're pregnant. Sometimes pregnancy symptoms are all in your head, so a test to determine your actual pregnancy would be best before you make any further plans or choices.
