I have really irregular periods. My last period was a little less than a year ago. I was recently put on the lowest dosage of birth control. On the third week I got my period (about 3 days early from the 4 th week of being on birth control). At first my period was normal, but now my period has gotten a lot heavier. I don't know if it's normal or not. For now my physician told me not to take the fourth week of the pills and to start a new pack this following Sunday. I am now on my 6th day of my period and still having a heavy flow, could it be my body getting adjusted to it?
