"had sex on ovulation day and condom broke. he didn&#039;t finish inside me, only a little got in me as he pulled out. i had just began my bc a couple weeks prior and was scared my antibiotics i was on could have interactected with my bc. so i took plan b 30 minutes later and started my period 2 weeks later on the predicted date! it was extremely stressful. i convinced myself at times i was pregnant by googling everything possible. i know it&#039;s hard not to do that but try not to! if you take it in enough time it should work. i had minimal side effects. lots of stretchy white discharge for two weeks and my period started as a dark brown discharge that was minimal and turned into a period. good luck!"
