emergency contraception
"I was on antibiotics & taking birth control pills, of course when taking some antibiotics it cancels out your birth control. To make a long story short, me & my boyfriend had unprotected sex & felt like the plan b pill would be the best choice of action. I took the pill about 12 hours later, the only big side effect I had was my period lasted for 22 long days! Did the pill work? Yes. Would I recommend it? Yes, just be ready for the side effects. I'll take being on my period for 22 days over being pregnant any day!"
