I had sex on the 5 day of my period and the condom broke. So I got the plan B pill within like 12 hours of sex. I then less than a week later got my period again for about 3-4 days. It was like a normal period. But I was supposed to get my period 5 days ago. I'm a lil freaked that the plan B didn't work. An I'm not sure if I need to go take a pregnancy test or if this is normal.
