Slimy blood?

No

I took the pill for about a month and stopped because I didnt like the side effects and how long & heavy my period was. I was just impatient to adapt to it. Anyways, I stopped about 2 weeks ago and I had unprotected rough sex 2 nights ago and it's been awhile since I had that and my body is really sore and so is the opening of my vagina. Anyways, we used the pulling out method. But I checked today and there was like a mucus like blood when i checked my underwear? Was it because he want rough on me and did that?
