emergency contraception
"I have taken the Plan B pill on two seperate occasions in 2015 and 2017, both times the pill was taken after contraception failure (condom breaking) during charted fertility window. I have given the pill a 5/10 review as I have had two contradictory experiences. 

2015: Plan B taken 8 hours after contraception failure during fertile window. ~5 days after taking the medication, bleeding resembling the flow and duration of a period occurred. No other symptoms noted. Induced period came approximately 1.5 weeks early. Not pregnant.  

2017: Plan B taken 30 minutes after contraception failure during fertile window. Sore breasts and bloating within a week of taking the medication. Missed period. Pregnancy confirmed by store test and physician."
