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 .
i tried the same method the day after this more recent incident occurred , but after taking the second dose , i began vomiting uncontrollably for the following 9 hours . since i threw up the pills , is it safe for me to try this method again ?
