So I got my period this month of January on the 1st. It lasted till the 5th. My period have always lasted about 4-5 days long and I'm usually never heavy. I ended up having sex with my man on the 8th and the condom busted but continued to do it w/o a condom. I ended up taking a plan b 2 days later so the 10th, and i ended up getting my period on the 15th and it only lasted for the day and I was heavy, somewhat. More than usual. I was bleeding dark red as well. Should I be worried or is it because I had ended my period about a week ago?
