i had 2 MC's within 5 months and my doctor just put me on progesterone and baby aspirin. my doctor is a fertility doctor that helps when get pregnant so i believe in what he says. I think that after you get pregnant and are through the first trimester, they then might want you to stop but it is safe especially for TTC and the first trimester.
I say if it's working continue... maybe get another doc's opinion. As long as it's a low dose there shouldn't be a problem.
The reason they say no aspirin is because it can cause bleed's in the baby's brain and stuff like that... But also... they say no IBPROFEN.. (in second tri. it's ok sometimes)
and It's got something to do with the heart,
Oh, I see another part of your question now- yes, fish oils also thin the blood.
I'm not familiar with the mutation you're referring to. But I do know that some people have to take aspirin through their pregnancies due to genetic blood clotting disorders (they are more likely to get clots). Usually aspirin is not recommended during pregnancy but I guess in the cases of ladies with blood clotting disorders the benefit of taking the aspirin to prevent blood clots is more important than the risk of taking it. But if it were me, I would want a doctor to suggest it and monitor it. Maybe you should see a specialist.
i wouldnt take it unless advised by a doctor, it can be unsafe. you do not want to thin your blood too much, but if you do continue to take it, stop around 32wks so you don't bleed too much during/after labor. i was order to take baby asprin with my first pregnancy b/c my blood wasnt flowing properly and they only advice was to make sure to stop ahead of time before i had him. congrats on the pregnancy and everything going well so far!!!
