Help, possible STD?

I had sex twice last week with two different partners, unprotected. Now for the past few days right after my period, I’m having a fishy smell. I had a similar experience when I had BV before but I’m not have a crazy amount of discharge like I did when I had BV, it’s just the fishy smell. No itching. No burning when I pee. Just the smell. Does that sound like a possible STD? I will see a doctor in the morning. I don’t think it’s STD related considering that everything was fine right until my period came and left and then came the smell.

And if you come on my post with judgment, you will be muted. I refuse to argue with people.
