Discharge Discharge🤦🏾‍♀️

So i had sex in December unprotected for the first time ever. My boyfriend was check out before to make sure and he was clean. He is uncircumcised tho. About three weeks after i started getting discharge like this and it has a smell to it. Not fishy or super strong. Can anyone help me? It itches sometimes but not always my mom thought it was a yeast infection so we treated it and it stopped and went away but my period went off earlier this week and it came back
