I'm very sorry for your loss :-( I was on effexor a few years ago... made me sick.
I had a miscarriage a few days later. I'm completely blaming it on the Effexor
I personally stopped taking mine and I was fine. My symptoms were pretty severe before pregnancy but honestly I felt fine pregnant well aside from the obvious mood swings lol
i used to be on antipressants..i went to the pharmacist to ask what affects they have in pregnancy..pharmacists know more about actual medication than drs..i stopped taking mine but my sister has been on the same ones as the drs decided she needed them..shes got a perfectly healthy 3 week old baby girl now..id deffo find out as much as you can good luck :)
There are other anti-depressannts that are much safer to take during pregnancy. I think you should get a second opinion.
Please get a second opinion just to be sure and get reassurance ASAP.
