Hello ladies!

I’m going to start with the background information I’m 18 my boyfriend is 23. I stayed with him from April 21st-April 26th, which wasn’t apart of my fertility window we had sex at least one time 4 of those days (usually initiated by me for those who might think I’m being used).

Some of those times we were having sex with a condom other times we didn’t but one particular time when we used a condom when we were done he pulled himself out of me and the condom wasn’t on him we freaked out. Scared his cum may have gotten inside of me, so we fished the condom out which wasn’t far from the surface (which I see as a good thing) we didn’t think much of it after we got it out. But Now as the picture below shows I should be on day 4 of my period but day one hasn’t happened yet... Any Advice ?
