I have been off bc for 6 months previously on it for nearly 15 yrs. I have had irregular cycles since getting off running 28- 34 days with occasional spotting. This month I got off my pd on the 3rd then had heavy spotting on the 14 &15 light spotting on the 16&17 and then none on the 18&19 then today I have heavy spotting again. To the point that I am using a tampon Again. What is up? Is this my period for the month possibly? I don't understand.  I'm not supposed to get it for 10 days but I have basically had one on and off all month now!
