Chemically smelling discharge

I’m a bit worried yes I’ve spoken to my Doctors been tested alllll clear ..

Today I noticed that my discharge smelled a bit acidic and I don’t know if that’s normal clearly it’s not because it didn’t smell great my doctor said I don’t have a yeast infection or BV.. or sti 😓

Any advise to get rid of the smell ?

This has just happened today , I did have sex with my bf last night and all this week as we are ttc .. so I don’t know if it’s the smell of his sperm messing up my PH

Advise ?

And yes I washhhhh 🙄 the smell only came today
