Personal embarrassing question.

Breeanna • mother of 1 beautiful baby and 1 angel baby. been TTC ever since my miscarraige
Okay so this is embarrassing but here it goes.. my husband and i are ttc. Have been for 16 months. I have never had this issue. Ik mens cum had a distinct smell but the last few days (havnt had sex) i smell like sex(or cum) down below. I have cleaned and scrubbed u name it wipes etc after a few hours... the smell ia back.. is thia normal? I have tested for yeast and uti both negative.. any ideas? I have never ket a smell this long. Maybe like an hour after sex but not for days
