Question

I am <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and bbt since cycle day 1 I'm now cd13. Feeling some sharp cramps in my left ovary. Any idea what it could be? Also my husband and decided this cycle to just bd every other day until AF is suppose to be here. Hoping that'll up my chances of getting pregnant? Anyone else try this and end up with a BFP
