Who would you listen to?

So I see a lot of controversy on here when it comes to pregnancy and meds and just everything. If you were prescribed a medication from your OB and people on here were telling you not to take it and you're risking killing your baby! What would you do? I've had the same OB for 10 years and have always had the same medication for every pregnancy. I catch hell because I'm on certain meds that has risks but benefits. Honestly, these meds have saved me and helped me to function daily.
