I had sex about 10 days after my period unprotected for about 5 minutes. I took the ecp about an hour after and got a light period 4 days after that only lasted a few days. Im pretty sure it was my period but it could have been spotting. Ive never had that before so I dont really know

today, about 17 days later I got another period that feels more normal and is heavier. I also feel tired and have cramps..Etc.

This seems like a lot of periods in a short amount of time..Im usually pretty regular and wondering if this is just due to hormones or has something to do with taking the pill? Ive never had a situation like this before.

Im not too worried about it but am wondering if this is a sign of pregnancy or due to some underlying issue. Any advice would be helpful :)
