Stopped using birth control 1 month and 2 days ago, have had unprotected sex with the boyfriend and still no period. I have been peeing a lot more like every 20 mins it seems and my tummy feels funny and i have been kinda gassy. Im not sure what to think really. Cause for the 6 months i took birth control i never took them regularly. If i forgot to take them two days in a row i would start bleeding and i would remember to take them but now i have stopped completely taking them and no blood at all.
