So here is what happened. My last period ended on December 5, 2011. Me and my boyfriend had sex on December 9. We used a condom but unfortunately it broke and we did not notice in time. We immediately went and obtained the Plan B birth control and I took both pills right away as instructed, no more then 2 hours after the condom broke. About 3 days afterwards, I began to bleed again. It couldnt have been my next period because of how early it was, and it only lasted about 3-4 days. Now, it's January 4th and I feel as though I've been having pregnancy symptoms. I feel very bloated, frequent urination, fatigue and for about 5 days around the same time at night I've experienced nausea. I haven't had a period since the bleeding after taking plan B. I'm really worried I could be pregnant. Is this a normal response to plan b?
