I use 28 day cycle birth control pills. I have been taking them for 7+ months. I occasionally forget to take a pill at the scheduled time so I take it later or the next morning as I take them at 10:30pm. I will always still take the pill. I just had my period and am now on week 1 of my pill pack. I was late, meaning forgot at 10:30 took at about 11:00 the next morning, earlier once this week. On my period tracker it says I should be ovulating today or tomorrow. Will I ovulate by taking a pill late? Are you supposed to ovulate the week after your period? Can I be pregnant after sex today? Should I think about taking an emergency plan B pill?
