Period sex,condom slipped, plan b, and pregnancy tests.

Alright, so I’m no stranger to plan b. I’ve taken it twice already. But, it’s never made me this late. I took it in December and then again February first as ,of course, I should’ve. The condom came off inside me and (tmi) but we physically had to get it out of me. It was the last day of my Aunt Flo and I had the immediate bleeding after words on the 6-8. I was supposed to start a week ago and I had symptoms like I would start and I’m even bloating, cramping, having my usual discharge the whole thing but that’s faded off and now all I have is cramping and bloating. The CB tests I have taken came back negative, the first I took in the afternoon (after I was five days late) and second one that following morning both BFN so I’m wondering if it’s the pill or if they were false negatives. What should I do?
