My boyfriend and I have had rough sex the last few times we have had intercourse and I noticed light bleeding about four days ago. I am still bleeding lightly and I am not due for my period until next week. I am on birth control but we no longer use condoms. I have been checked with him for STD's and I am STD free and I know he is faithful. My uterus also has pain. It is not too uncomfortable but I do notice the pain sometimes.

Should I take a break from sex until the bleeding subsides or should I contact my doctor?

You should contact your doctor to rule out uterine or ovarian fibroids. Also, I would recommend that you sustain from sex until the bleeding stops.
