Should i see a doctor? Im 16 and im at the Beginning of my second pack of reclipsen birth control. I had withdrawal bleeding in the last week of my old pack. I started the new one while i was still bleeding. I continued to bleed for a couple days. Then it just turned into a brown stringy mucus that sometimed had red in it. The mucus continued for days after and still occurs. I had sex for the first time in a week and started bleeding after. Then i had sex the next day and the same thing happened and the mucus hasnt stopped. What should i do?
