Strange period

Dara

Ok girls! My period came on December 8th it was 1 days late and I had a light flow the first day as usual. Then on day two it was medium red blood with a few very small clots. Usually by day two and three I’m a heavy bleeder. Well by day three the bleeding stopped and every time I would wipe it would be pink spotting, nothing on my panties just when I’d wipe. Well today makes day 5 of spotting. It’s really light now and barely visible but it’s still there. I’ve taken two pregnancy test both which are negative. I’ve been having cramps and back pain this entire time and my boobs are sore. I’m not sure what’s going on with my body. Has anyone else experienced something like this? I’ve read about fibroids and endometriosis and I just don’t know what’s up. I’m usually very regular and bleed medium and heavy for at least 5 days and usually one day of spotting. Just looking for past experiences! Thanks ladies!! Here’s a pic of my last test.
