I can smell my vagina through my pants ..

When i wear sweatpants sometimes i can smell the odor of my vagina, it’s not horrible or fishy or sour but i notice it and i wonder if other people notice it or if it’s just me noticing my own scent.. i know that i have a lot of discharge my underwear is wet after about 4-5 hours of wearing them with just clear discharge. I used to think this smell was from my boyfriends semen being inside me but he’s currently been away for some months and im noticing it still, but i suppose never had this problem as a teenager cause i never noticed it . I’m 22 now by the way and I’m noticing it now a few days after my period
