I'm so sorry about your losses, I can't imagine. Just can't imagine.
I'm with you about the crying and getting depressed when AF comes. The cramps and fatigue that come with it are just like blows when you're already down. I told my husband to tell all his friends that the next one who asks when we're going to have a baby is going to get punched! j/k (okay, not really).
My husband did bring up a good point when we were talking yesterday though. We've been focussing on bd'ing around my peak or ovulation day. He brought up how the days leading up to ovulation are more important than the days after. So if I figured I o'ed on day 14, instead of bd'ing from 12-16, we really should from, like, day 8-16 because of how long the sperm can live in your body. Just a thought, I'm in no way an expert though.
Good luck, blessings to you, and let us know how it goes!
