Hello. I had an abnormal pap smear about 4 years ago and was supposed to have a biopsy to make sure it wasn t cancerous. I read about it and got scared and so I never went back. Since, I have had one normal pap smear so I figured it was just a fluke the first time. I am currently 27 years old and when I was 21 I was with a partner who said he had HPV but it was not the strain that caused genital warts. I have never experienced them. When I was in the shower today, I noticed a small, smooth, round bump on the opening of my cervix. I have also been having really weird periods. I have been bleeding between periods (brown spotting,) have bled after intercourse, and have recently had an increased amount of brown/mucous discharge. It has gotten so bad that I need to wear a tampon. When I take it out, I am also noticing what looks like uterine lining in the toilet after urination. I m not sure if it s a period (I currently am experiencing the discharge, though my last period was 2 weeks ago, lasted a week, and went away,) or if these are all symptoms from my Nexplanon which was implanted in October 2014. It s currently April 2015.Any help or advice would be greatly appreciated. Thank you!
