I had sex before five months, but then I got my period after 15 days. Then, I had no periods for the next four months. I had Femilon as a birth control medicine. Now, I have periods with large clots. A piece of it is still stuck in my vagina, and I am not able to pull it out. Please let me know what it is and how it can be taken out. I also have a PCOD problem.
