Hi there! July was my first month TTC baby #1. I ovulated and BD on my days. AF due today but I don't have any of my normal symptoms such as bloating, lower back pain etc.. Took a Pregnancy test last night and got a BFN. If I'm ovulating and my husband and I BD on those days, could it be an issue of my husbands sperm? Or the timing? Thanks
