I just had sex with my husband, i noticed some red discharge right after, it went away after wiping myself after using the bathroom, should i be conc?

No: There is some degree of trauma to the vaginal tissue during intercourse. As a result sometimes you experience some bleeding after intercourse. Additionally, lack of lubrication can also be a problem resulting in some bleeding. If this continues try using some lubrication.

Cervicitis?: Bleeding after sex often means inflammation of the cervix (cervicitis), often due to STDs (gonorrhea, chlamydia). And you chose topic tags gonorrhea, chlamydia and STD, showing they are on your mind, which probably means you think there is STD risk. So definitely get care and be tested. Also check for bloody semen in husband, which isn't rare (usually harmless if only once or twice).
