So according to glow my peak day was yesterday. I started to have a twinge of pain on my left side of pelvic area but my opk was clearly negative. I hade the twinge of pain all day. I took and opk test this am and it looks positive. We had sex last night. I woke up with the twinge this morning too. Should I have sex tonight too? I heard doing it every other day was best. I just want to make sure I cover all my bases. The first pick was yesterday mornings opk and the second is this mornings.
