inside vag itching

so my boyfriend and i have been having unprotected intercourse for a few months now, after the first time we did anything unprotected i went and got tested for stds( i know we should have done that beforehand) but it happened. i got tested like 2 weeks after that happened and everything came back

normal. but here recently i’ve been having egg white discharge sometimes sticky sometimes it’s like lotion and doesn’t

stick. it doesn’t smell any different. but i have noticed i do get a lot of discharge and it’s been itching inside of my vagina. what should i do??? how can i prevent this stuff from happening
