So I am on tri estryella Birth control and I take it on time every single day and I’ve been on it for over 6 months! I have gotten all my periods but also just gained weight this holiday season! Sometimes I think I feel twitches in my stomach but I’m not sure. When me and my boyfriend have sex he does not finish in me so if that helps with anything! I don’t know if I’m pregnant or not and it’s my worse fear!!!
