So my periods have been everywhere. I might have PCOS but not sure, get blood results on the 6th. So the glow predictions for my periods are pretty useless. I had sex 2 days after my period ended, and I know sperm can survive for 5 days, so I was wondering if there was any possibility that I ovulated between the 10th and the 16th? It would mean I’d have a short cycle, but I’ve had cycles from 21 days-165 days. And I’m not sure if it’s worth it to take a pregnancy test or not, because as you can see we only had sex twice this month.
