Im 17 years old. I was on the NuvaRing for 2 months, i had unprotected sex the whole time. After the second month of the NuvaRing, i took it out and never had a period? I took pregnancy test after pregnancy test, negative... 3 months later I'm bleeding. It started off as dark brown blood and now it's bright red. I don't know what's going on? Help please? The thought of being pregnant for so long has made me want a child. I also have endometriosis and need to hurry on having one.
