so early monday morning , my boyfriend and i were having sex and our condom broke . i have levonorgestrel at my disposal , but i haven't used it as a regular birth control . we had a similar situation a few months ago , and i used 4 pills of levonorgestrel immediately , & then 4 more in 12 hours following the first dosage , as recommended by a university healthcare website . everything worked out fine , & i felt very mild abdominal pain .
