So, why would you take plan B when A. you used a condom that didn't break. B. he never ejaculated into a condom. And C. you were finishing your period so it was very early in your cycle? I ask because Plan b is for emergencies and taking it too often will mess your hormonal balance up. That was over kill and unnecessary. If a condo breaks, yes, take it within 72 hours. But that should be a very rare thing. You now will likely be late, irregular, having spotting on and off for the next 2 to 3 months which is normal after plan b. Plan B is a big dose of hormones which is how it works. But then those hormones are in your system. So, no. You are not pregnant. Bacterial vaginosis is unrelated to all of this and the symptoms of that include very foul smelling discharge that is thin, grey and watery. good luck
