So I have a three month supply of birth control. I only have my period every three months. And yes, I am sexually active. It's with the same amazing guy that I've been with for almost three years now. Last night I took my first pill thats just a reminder to help me keep track of how many days im on my period. This morning, I've only had the tinniest bit of bleeding. which is unusual, this is my third package of these pills. The package says that if you don't have a period while taking these fillers that I may be pregnant.. I'm only 16 and couldn't handle that... So, I'm feeling a little bit of cramping but I'm still paranoid of the pregnancy thing. Should I worry?
