I started the pill the Sun. after a cycle as prescribed. Since then, my usual 3 to 4 day periods every 26-28 days have turned into me having a 7 day period from the end of Jan. (22 days after last period) and then another which started on the 12th of Feb. and is still on now. This cycle goes from on to off, off to on, heavy to spotting, spotting to heavy... it's all over the place. I'm getting married in Aug. & have another wedding to be in in July so I am trying to take them until at least July, however, this is frustrating and I don't know what to do.
