Hi ladies, 2 days ago me and my boyfriend got caught up in the moment and we had sex for like 3 minutes and then stopped and realized we didn’t have any protection on.

When I got home I peed and wiped and there was very very light red streaks of blood in my cervical mucus. Then yesterday morning it was a little more but still very light and then today this morning it’s now light brown???

Is this implantation bleeding?? Can it happen this early?? Should I even be worried it was only 3 minutes?? He didn’t cum, and he didn’t ejaculate the whole day.
