Hi. I m on Sprintec ( norgestimate and ethinyl estradiol ... 0.250 mg/0.035 mg). I m usually very accurate with my bc, but i ve been recovering from an intestinal infection in addition to a bladder infection and haven t been myself lately. I was supposed to start my new pack of bc on March 13th, but didnt until the 14th, because that was the soonest i could get my prescription. After driving 12 hours yesterday, I forgot to take my pill . I doubled it today, but didn t realize i had forgotten it until after i had sex. My question: Should I take plan b just to be safe?
