So I've been having a very irregular period...ive been on it for 9 days now. I am on birth control but i just had my period a week before i started it agian. Ive been a little dizzy and lightheaded and me and my boyfriend have unprotected sex sometimes, but he pulls out and we use condoms as much as possible. My boobs have also been soar, ehich isnt normal for me and ive never had an irregular period. What could be wrong?????
