<s>[INST] Hi, I am taking Tri-Sprintec (generic brand of Ortho Tri-Cyclen). Now that I've started my 2nd semester, I've been distracted with HW and sometimes end up taking the pill 1-3 hrs late or earlier than the day before. Is this much inconsistency bad for me? I always use a 2nd method of protection, but I wanted to know how much my inconsistent patterns effect the pill. Thanks! [/INST] Hi, Iconsistency of 1-3 hours is acceptable. But try to be as regular as possible. Also if you miss one day then take two pills the next day. But if you miss more then you have to use another method of protection like condoms for the rest of the cycle. </s>
