My last period was Oct 26-1st I think I ovulated Nov 8th that should be cycle day 14 if I counted right. I had sex on the 7th and used preseed. Glow got my period wrong for last month so It is wrong for this month. I don't usually know when my period come because they are irregular. Is there a chance I could be pregnant I don't want to test because I don't want to get my hopes up. I've had really bad pains in my lower stomach for like 3 days it was on and off, headaches, and my nipples been sore. I'm not gonna test until I'm at least 2 weeks late
