I’m so confused 😂

Acasia

So I had sex the beginning of this month which was a few days after my “fertile window” making the day I had sex the day I was supposed to get my period but didn’t. I did have some ovulation like discharge starting a few days after sex and with PCOS I can’t for sure tell if that’s what it was or not. My periods are all over the place. Friday I started to experience sciatica pains. Saturday came and it was much worse and I started to feel some pelvic pain and that’s when the spotting started. I chalked it up to my tensing from the pain or possible cyst bursting. But I looked at the calendar and it was about 14-16 days after sex. Strip test was negative. Idk if I should test again now because the type of bleeding looks similar to the kind women who were pregnant had.

The spotting can sometimes be on and off and it can be none there or a little bit like this or a small amount of a brighter pink but still only a bit and then back to being this light again and occasionally creamy too. IM CONFUSED LOL What is going on with me
