Vaginal smell :(

I shower everyday, and always use ph balanced cleanser. However, over the past few weeks I have noticed a smell. Straight after my shower and a few hours after, there is no smell. But after a few hours, I can really smell a strong scent coming from my vagina. If I squat on the floor, or bend over I can smell it, and it’s definitely from my vagina because the smell is the strongest when I take my underwear off :(. What could this be?!

Background info: 19 years old, was on progestregon birth control for 2.5 years and came off of it about 5 months ago, I have unprotected sex, in a very committed relationship (they have never been with anyone else apart from me, and I haven’t either), not due my next period for 11 days.

Thanks everyone <3
