Not feeling hopeful.... 😢

Kayla • Married. I have a 11 year old. We are finally pregnant with #2 due December 2, 2018!
I'm really not feeling hopeful this month. I'm 10 DPO and I feel normal. 😩
My temp is sill way above the cover line. However, I took an OPK this morning and it was negative. I've heard from some other ladies on here that if you get a positive OPK a few days before your expected AF that it could indicate pregnancy. 
I'm still going to wait until expected AF (4/4) to take a pregnancy test.
Hope everyone else is doing well!! Baby dust!!!
