Hi im a bit worried but im not sure if im pregnant or not. im on birth control pills and on the 25th of march i had my normal period for 4 days. on the 29th and 30th of march i forgot to take my pills and on the next day i started bleeding. so i took my pill and the bleeding stopped but i had unprotected sex. the next 7 days i've had bleeding in the middle of my pack and now i have brown discharge and feel sick at random times in the day.. could i be pregnant?
