Std? Bv? While pregnant

So I recently found out I’m pregnant I am 6w3d and before I found out I had what I thought was a yeast infection so I did the monistat day 3 and then as it started going away I noticed sort of greenish discharge ? But then all the symptoms went away. So now I have like a greenish tinted discharge again but no itching or anything and the discharge has never smelled bad. My first appointment is May 4th so I don’t know if to wait till then to get tested or call my doctor now to get tested ? The only thing is that my insurance doesn’t cover everything so I would have to pay around 200 maybe more. So what do you ladies think?
