Preseed

I’m sooo on the fence about using preseed! I’ve read review after review about how women say it works and they go on to have a healthy pregnancy. I have also read many reviews saying that the preseed allows weaker sperm in resulting in a miscarriage! I just went through a miscarriage a few months ago so my husband and I are scared of loosing another baby. My husband is in the military and he wasn’t home through my ovulation. When he gets home it will be a week before my period. Should we use preseed then or wait until the next ovulation?

Thanks!
