Vaginal odor

My husband and i are ttc and last night we had sex. I normally go to the bathroom right after but I heard you should wait a little while to make sure it all gets where it should go. I woke up this morning with a funky smell down there and idk if it’s from his semen or what. It’s not a very strong smell but I definitely noticed it. Should I call my doctor or is it just from sex? I took a shower and rinsed everything really well with water and it’s still there 😑
