hi ladies! i keep getting whiffs of urine and im not sure if its me? i went and checked and my knickers have a stronger smell but not necessarily wee? i seem to have wet patches at the top and round the back of my knickers but not enough that i think ive pissed myself if that makes sense?

Ive been sitting for lunch and noticed this on the chair?

The below was my opk for this morning but it probably not related?

I shower everyday so im not dirty, just concerned so please no nasty comments🙈😭
