I need advice, please help!

I had intercourse at the beginning of the month the condom broke but his penis was outside my vagina still touching the outside though. Then, I had intercourse three days ago and experienced bleeding that didn't last long at all was done before the night was over. I was expecting my period for today and it did come today, but I had a dark discharge before today not a lot but noticable when I wipe. This period seems normal. Although, I looked on the Internet and some say early pregancy, just worried! Anyone who might know what this means? Could it be because my cervix drops before my period and caused the bleeding and dark spotting until today my actual period? Please help, I could use some advice!
