Hello, I've been on sprintec for about 7 months now. I usually start my packet on Sunday but due to a prescription mess up I wasn't able to start my new pack until Thursday. I take the pills everyday at the same time. I went out of town and missed my last 4 active pills of this month meaning I only took 16 active pills out of my pack... I'm now on the fourth day of not taking any pills and im not having any bleeding and I also have not had sex since my last period. We did do a little foreplay but I was careful that he didn't touch himself and then touch me. Is my period late because of the mess up with the pills?
