I am pg with my 3rd child, 1st baby conceived normally and had a normal pregnancy. Then had 2 mc. Discovered I had Antiphospholipid syndrome which can cause mc. My next pg was the result of clomid treatment and from being 7 wks pg had to inject certaparin evry day till delivery. However I became allergic to certaparin and changed to similar drug tinzaparin. Anyone else had these injections. I also took 75mg Asprin up till wk 34.
