I take Qlaira ( Natazia in the USA) birth control. I'm a sonographer as well. I skipped a week and started the next pack 7 days past when I should've after finishing my previous pack. I scanned myself and noticed my endometrium thickened to 7mm and I ovulated on day 11 (yesterday). I've been taking it for the past 5 days though. Am I still protected against pregnancy?. Sonographically id say no but not sure about hormones. Advise please!
