I'm 19 years old and I'm on the pill Camila and have been on it now for 3 months, first I was on the IUD called the paragaurd. Now, my concern is that I keep bleeding, it stops for 2 days and I keep getting it back, even when I have sex. Should I be concerned? This doesn't hurt me in anyway and I did about a month ago got my appendix removed because of pains and I had a cyst on my ovary. What could this be? I'm scared.

It is possible that your body is just adjusting still. Some women will have irregular bleeding at first, some will even have it continue as long as they are taking the pill. If it continues, and only you can decide how long is too long, you may consider a different pill to try. Certainly wouldn't hurt to talk to your gyne about it.
