I have been on the pill for about 7 months now. I am currently taking Tri-Sprintec (28day pill pack). I missed two days in the first week of the new pack (this past Sat & Sun), I started this pack last Thursday. I am following the directions on the pack, to take 2 today and 2 tomorrow and I should be back on track to 1-day on Weds. I was sexually active the Sat & Sun I missed the pill. Should I take Plan B? I called my local pharmacy and they pharmacist said I should be okay.
