My boyfriend and I had sex on December 31st with a condom on, but after we finished, we saw that the condom broke and he came inside me. I took an emergency contraceptive within 30-40 minutes after that. Then on January 7th, I woke up and I had light bleeding . It wasn’t like spotting, it was more like a sign that I usually get when I begin my period. However, I am uncertain if this is my period or whether it has anything to do with the chances of me being pregnant. I have a very irregular menstrual cycle. I only experience my period a few times per year, and I just had my period a couple months ago. It is unusual for my period to come this early after the last one, and the cramps are much more painful than my normal period, which is very light cramping. A day after that, on the 8th, I started to bleed normally, as if I was on my period. Then today, on the 9th, my bleeding almost ceased. There is only a little blood, but it is more than spotting, like light bleeding. I have not gotten any other symptoms besides cramps, and it has been 10 days since the night we had sex. What are the chances that I might be pregnant, or could this be a side effect of plan B??
