I messed my birth control for week and half because I ran out and couldn't get a prescription. She I got the prescription I noticed the pharmacy gave me a different brand. The doctor told me that I could start taking the new pack that night. Well the first month, I hardly bleed and in fact only had one wipe of light blood. That's it. Second and third month no bleeding. I've been moody and had bad cramps the weeks I was suppose to be on my period. I've taken pregnancy test each month and all came back negative. I'm suppose to start a new pack but I'm afraid I messed up my cycle. I don't know if I should start the new pack or wait until my body regulates itself. My period has always been regular. I never have had as bad cramps with the exception of these few months. I'm not sure what to do.
What should I do?
