No period on tri sprintec?

No period on tri sprintec?
A little background information first. I've been on tri sprintec for about 3 months, went on it 2 weeks after a miscarriage in December. So this would be my third month I guess. Its the 4th day of the sugar pill week and my period has not started. I took two pregnancy tests, 1 yesterday at 1:30pm and another this morning at 6am and both tests came back negative. What could be causing my period to not start?

Your period can come any time during the placebo pill week. Don't freak out unless it hasn't come yet by the time you start a new pack of pills. Then I would contact the doctor.
