this is embarrassing..

Okay, I am 25 years old and I've struggled with an abnormal smell down there since before I was ever sexually active. I've had many bacterial tests done and everything has always come back normal. Idk what else to try anymore...
My questions is, are any of you ladies brave enough to let me know if you have ever experienced the same thing and how you were able to treat it? I've tried soaps, sprays, just simply rinsing..it's worse after my husband and I have sex, when I sweat a lot, or if I'm super active. Idk what else to do and it's absolutely embarrassing..Now that I'm 32 weeks pregnant I'm getting more and more embarrassed for check ups..please don't be mean, I am truly embarrassed by all this.
