spotting (heavily) mid cycle?

Brenna
I’ve been in a serious relationship with my boyfriend, and we’ve been intimate almost from the start. He doesn’t use a condom but he never finishes inside of me, and I know that’s not a full proof method to prevent pregnancy, but we’ve not had a problem with it before. Recently, within the last day or so, I’ve started spotting, and I had my last period about two weeks ago. I’ve never had issues spotting like this and I’m cramping as if I were in my regular period and my flow is getting a bit heavy. At this point it looks like it would if I were on my regular period. I’m not sure if I would call it spotting at this point but I know there’s no way I’m on my period again so soon, am I? Recently I also stopped using my birth control, but I had only been on it a month as I’m supposed to be getting an IUD within the next few weeks because I have issues remembering to refill my prescription. But this still has me stooped as to what’s going on. Any advice would be appreciated, thanks so much!
