My vag

I'm almost healed from birth but i noticed tonight that it has a off smell nothing overpowering etc how soon could my period come back.. I'm nursing and yes me and my husband has had sex already we just couldn't wait any longer I made it to 3-4 week mark 😅 and I'm going camping this weekend it's not a uti because it doesn't hurt to pee or anything just wondering...

Just advice I'm not going to the doctor
