... injection in the month of July 2014. Sadly my insurance got canceled. Since then I have not been on any birth control. A month after I was suppose to get my injection, I started my period. Instead of getting it monthly, I got it every 2-3 weeks. I am still sexually active, no protection, just pulling out before his "excitement" happens, and now I havent gotten my period. Its about to be a full month since I have had my period. I am just scared that I could be pregnant.. Is it possible that my period is becoming regular?
