My periods have always been relatively irregular, as my cycle is somewhere between 38 and 45 days. My boyfriend and I had sex and he pulled out well before he got off, and I also went to the bathroom afterwards. I am having all my pms symptoms but not physically starting to bleed or anything. When we had sex I wasn’t in my fertile window, so I feel like the chances are really low (we had sex around a half-week who). Should I stress about this?

It happened a long time ago with someone else, but I tested and it came back clearly negative.
