I am on my 3rd month of being on Tri-Sprintec. Last month I missed one pill but took two the next morning. I had unprotected sex one time but he did not ejaculate inside of me. My period was very light the week I had it. Just a little spotty for a day or so(worried that it was implantation) This month we have had sex plenty of times with a condom and I have been taking the pill religiously at roughly 7:45 to 8 am everyday with one dis recently being at 11:30 am. My period is supposed to come this week but I haven't had it yet and I'm worried I'm pregnant. I've read that it is normal to miss a period or for it to be late on the pill but I'm still worried. Thanks
