Hi, ive just started taking the birth control pill called micronor on the 2nd of april, which was a monday cause i started my period then. my period finished on the 6th on a friday. I had unprotected sex on tuesday the 10th, and then on the 12th i had some brown discharge on my underwear. i had this brown discharge for 4 days now. its the 16th. ive just started to feel lower back pain, and it wont go away. ive had headaches for the past week, they come and go. i dont know what to think at this point. ive never had this discharge before. i also havent been taking the pill at exactly the same time. i take them at 8 in the morning, but sometimes i take the pill a few minutes late like at 8:15. i just was kinda thinking that i could be pregnant, cause i have a 6 month old baby, and the back pain feels the same but ive never spotted like that before. what do you think is wrong with me? Thanx for hearing me out!
