<s>[INST] I was with my boyfriend on saturday and the condom broke but he didn t realize until we were done. I am on birth control and Ive never missed a pill, but i haven t been on it long (today will be my 29th pill) Should i get plan b? Im hitting that 72 hour mark in about 2 hours [/INST] Hello dear,I understand your concern.In my opinion the plan B is needed in case of emergency situations like slippage or breakage of condom,missing a birth control pill etc.As you have regular intake of birth control pills there might be no need of plan B.But if you have missed any pill then the plan B can be taken.The plan B is effective in 95% of cases of taken within 72 hours of unprotected intercourse.The plan B effects the timing and bleeding of periods. So they might get delayed or come early and the bleeding can be scanty or heavy or irregular.Hope this helps.Best regards... </s>
