Unprotected sex two days in a row and noticed a foul smell? TW: mention of miscarriage

My husband and I decided to start trying for our final baby after experiencing a miscarriage back in May. My OB gave us the clear to try again after one menstrual cycle. I’ve had my first period since and so my husband and I decided to just do it as much as possible and just see if it happens. So far we had sex two days in a row. I use the restroom before and after sex every time. I woke up this morning and noticed after wiping there was a foul smell. I personally never experienced this before. It is faint but obviously noticeable. I have no other symptoms. No discharge, no pain, no itching. Is this anything someone has experienced before? Is this normal or should this be a cause for concern?
