ok! goin on 10 months here on OTC-lo.

the first 6 months.. period was GREAT! no cramps, 4 days long. all light. LOVED it! couldnt of been happier.

7th month.. a day late..5 days.. moderate cramps... i can deal with that..
8th month, couple days early, moderate to bad cramps..2 light days 3 heavy days 2 light days.
9th month.. around the time of my period.. bad-awful cramps5 day period..
10th month.. a week early, i just started my green pills today, when usually my period dost start untill i start my green pills. goin on day 5 .. still bleeding.. and the cramps were HORRIBLE. i havent been in that much pain since before i started bc.

what the heck is going on? why do they keep getting longer, and becoming more painful? i dont miss any, always on time. is this normal? when will they go back to the 4 day, light, no problem periods? i have no problems with otc-lo.. but this is really bugging me.

i have a checkup in april for the obgyn. and a perscription refill of my bc.. but i started taking bc to get away from these god-awful cramps. and i was fine.. but i feel like my bodys going back to how i used to be not on bc.. and i really dont like it.

any advice?
