Hello,
You and your BF use the pull out method and you are also on birth control. You had dark brown periods for 3 days 2 weeks ago and since then you are experiencing
abdominal pain. If you have correctly used whatever birth control you are using and your partner pulled out well then you may not be pregnant. However, the pre ejaculate does contain semen, little carelessness can make you prone to getting pregnant, such symptoms can also be indicative of
implantation bleeding.
You can wait for a couple of days, if you develop symptoms of early
pregnancy you should get urine test for pregnancy done. You can get clinically examined by a Gynae, get USG (
Uterus and fallopian) tube done to detect ectopic pregnancy or confirm pregnancy. If you are pregnant you will be managed accordingly. If not it can be due to
hormonal imbalance, PID, PCOS, cyst, etc. It will be treated accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
