Itchy vag. ... *TMI*

My vag itches like the inside of it no it's not a STD or nothing crazy Im very clean it just started before bed and my so is working a triple won't be home until 7am or later -YES it's lonely but that's a whole different conversation.,.. anyways I didn't use any new soap or lotions I took a shower today and washed up ..... I'm on fertile time right now so could that be why. ? **Now before someone comments well we aren't your doctor some smart comment obviously I know that** I just want opinions on possibly.. thanks
