I am 95% sure my menstrual cycle is every time 31 days. In the first pic it shows when I was supposed to ovulate, on the 25th through the 28 I noticed I had a clear and streachy cm. I figured I was ovulating late. I decided to have sexual intercourse on this days where the hearts are. A couple days after and now, my boobs are sore, I'm nauseous, moody, bloated and feel a little crampy. Last night I thought I was going to start my period but nothing happened. In the second pic, it says I'm one day late for my period. In the last 2 pics are my pregnancy tests that I took yesterday afternoon and evening. Is there a possibility that I might be pregnant?
