Pregnant w/ a funky smell...

Ok girls so I'm 7 weeks pregnant and stressing out Bc I have a funky smell down there... no weird discharge out of the ordinary but I know it's not my period coming either... I'm having sex less often with my boo Bc of it. and it's not Bc he doesn't want to, but Bc I'm stressing out about that funky smell when he goes down on me. I can smell it even right after I shower... any tips? is it safe to use douches while pregnant? Could it also be that my smell sensing is getting really strong? I doubt it...

PS. he has never complained about it ever...
