Do Things Look Promising This Cycle?? :)

Lydia • ❤Married #July1st2017 ❤
Today I'm on CD29/11DPO and my temp was 97.87° today, and last month on CD29 It was declining already because of my upcoming period and it was 97.70°. And this month's tests just keep rising! :) I'm still kinda nauseous, gassy, and I have A LOT of creamy CM. BUT I got a BFN on a cheapy test this morning. Should I just wait to test till I'm 18DPO or wait to see if AF comes? Do this cycle's temps look like a good sign to y'all? :) I'm 20 and my fiancé is 29. We had a miscarriage back in April 2016, and we put off trying again for a few months, and now this is currently our 3rd month of TTC again.
