Robin

Hi I'll be 43 in a few days and pregnant while I have a 10 month old I've had a loss before him and 2 more after I've been reading alot on folic acid and folate and aspirin my ob had me take a baby aspirin a day with my 10 month old but I was like 13 weeks or so should I start now I'm only 4 weeks but all my losses happen between 4 and 8 weeks also if I'm taking. A prenatal should I still take extra folic acid I dont wanna risk losing another baby if I can thanks for reading I know that I need to ask my dr but she won't see me for 2 more months just looking for advice from people that may be taking these thanks
