Sarah, you sound quite similar to me!! Approx 2yrs conceiving # 1 (our bubs are 8 days apart) & both not having an easy time conceiving #2. Fingers crossed for us both as my temps so far this month as not normal either (I am CD 15). Yours all all up & down & mine are just a bit neutral - not doing much. I sooooo hope we are both announcing BFPs later in the month. Goodluck with getting the thermometer sorted!
