Recently I had my teeth pulled & the dentist put me on Penicillin and i am on birth control!! Not knowing that it would affect my birth control. On the day after my cycle which was the 30 of October i had sex &the condom broke. Every since that happen ab 3 day after i began to have mild cramps & on the 14 of November I began to cramp extremely bad to the point I have to ball up and let them pass. For 4 days i have these cramps and when i go to the bath room no blood until I whipped and it was brown spotting. Now on Day 3 i began to spot more but it was very dark as well and my cramps are no better! I Really wanna know what are the chances of me being pregnant?? !!
