Since I got this birth control put in I only had one period and that's because I was late when I got it. Well I just went to the bathroom and when I wiped it was clear slimy stuff with blood through it.

I got the birth control in January. But I also had sex yesterday so could it be from having sex?

I'm a little nervous.
