So, this month AF came exactly one week late. I did text up until the day that she arrived and of course they were all BFN. So, AF lasted from the 8th until the 12th and seemed like a normal cycle. Anyway, here I am 5 days after the last day of my period and I’m having some back pain and some random, sharp abdominal pain that kinda feels like ovulation pain. This app says I’m not supposed to ovulate until the 28th (which I know is just an estimate) , but is it possible that I could be ovulating?
