Me and my boyfriend had sex 2 days ago. When I went to the bathroom to clean up I wiped and there was light pink blood on the toilet paper. Went to work and no blood for the rest of the night. The next day I went to the bathroom and wiped and seen light pink blood again. I've been spotting light pink for the whole night. I had my period on the 31st of December and been off since the 4th of January. What could this mean? It's the first time it has ever happened to me and I'm very worried. *** help!
