Unprotected Sex;
I am 19 years old and recently lost my virginity. Me and my partner had unprotected sex about 4 times in one night, but he said he pulled out before finishing. I'm not sure.

My cycle;
I was due for my period the week I had sex, but continued to take the biege active tablets to postpone it. I had only been on the pill for 10 days.

After;
I had my period about 2 weeks after having the unprotected sex. My period was seemingly normal, a little bit of clotting.

Recently;
My second period after the unprotected sex, is what I am concerned about. I experience some cramping and sharp pains inside my vagina. My concerning was the clots I found. One is particular was large, and clotted with white, pink, and red. It was like body tissue, all clotted but was like a skin texture. The smell was also strange. It wasn't like a normal period smell.

Help. I'm really unsure what this means? Did i miscarry, it is possible?
