Birth control & Irregular period

[PurpleTigger]

My periods have always been normal up until last month. I had a normal flow on August 22nd through to the 26th. Then I had another flow begin on the 6th of September and go until the 11th. This did not start out like my normal period and went on longer. I went to the doctor on September 8th for birth control. (Nuvaring) My question is: Am I supposed to expect my period around the old normal time or look for it at the beginning of the month now. I know you are supposed to put it in the Sunday after your period begins. I've used Nuvaring ever since it was introduced and never had a problem but like I said my periods have always been regular. Just want to know when to expect it. My boyfriend and I were TTC and I don't want to start BC without knowing I didn't miss a period. Please Help!!

Thanks. That's what I was going to do, but I haven't used any birth control since my son was born. We were trying to conceive one last time before putting it on hold for awhile and I just want to be sure before I start on it. It's such a concern because right now would be when I would normally get it and I have all the normal symptoms. Change in discharge, irritability, tenderness, diarrhea. I can't help but keep expecting it when I go to the bathroom. I've had an instance like this before, but it started right back up on the normal schedule. I wasn't on any BC then either. It seems like real bad stress will bring my period on early but it has always been back when it was expected. Like it was just an extra one. I wondered if anyone else had it happened. Thanks again.

Look for it at the beginning of the month because hormonal birth control can change it a little.

However you probably want to do a pregnancy test to see whether you are pregnant just to rule it out.
