Okay, so you took 4 regular pills right? Then you proceeded with regular pill use ?
The official estrostep pill use guide says if you miss three or more pills in a row keep taking the pills. But the next sunday after you miss the pills start a brand new pack. So basically do not allow yourself a placebo week. And do not have sex for at least 7 days. It says that you will still have protection, but it is lessened to a degree. Mostly sex you have after the missed pills would be more dangerous because it takes a few missed pills to increase chances of ovulation. So if you have not already, start a new pack!!!!! Do not have a placebo week!
