Urine smell?

This may be TMI...I’m sorry

I’m wondering if any of you have had this happen. My husband walked into the washroom right after I left and said “Are you in your period?” I was caught off guard because, no, I’m not. When I asked him why he’d ask that, he said “Sorry, it’s just that your pee smells different.” Anyone else experience a change in Irvine smell? I’m TTC, but haven’t been keeping up with things like I should be. I’m hoping this month will give me a BFP.
