Hey, I had unprotected sex about a 9 days ago. I am on Yaz, and have been taking it at about 2 am-3 am regularly for 2 weeks prior to the unprotected sex. The day before the sex I took my pill at 9pm because i was going out to an event. The next day was the unprotected sex, and i took my pill right after it at 4pm, thinking it would be a higher dosage and would protect me more, for the past week ive been taking my pill at 4pm regularly. My period is due about now and i am on the white sugar pills. However i have no period cramps. Just incase i took a regular pregnancy test 4 days before my periods and it came out negative. I am still worried, should i be?
