I recently started taking birth control. I had been off of it for about a year and a half. I started on a new brand loestrin. for at least 15 days during the first month i took it, mostly in the beginning on the month, I spotted. I finished off the month but contacted my gyn to get a new kind of birth control and was told not to take it until i got my next period. i have been off that birth control for about 2 weeks now and have not gotten my period. is it normal to not have my period yet if i spotted the majority of the month?
