I am on ava30, i have been skipping the sugar pills every 2nd month with no issues, but the last month i was a bit late with a few pills (not more than 12 hrs), then i got a breakthrough period for about a week, then another one about 4 days later then went straight onto the sugar pills. I didnt get a period on the sugar pills and assumed it was because i had already just had one, but if i wasn't bleeding and was on sugar pills and had sex several times am i at risk of being pregnant?
