Temps still rising but BFN at 12DPO, Am I Out?

Rachel

Have been TTC for 5mos and this is the 2nd cycle after my chemical in August.

I’ve been using tempdrop for the last month and I’m approx 12DPO (+cheapie opk and CB digital). My temps have continued to rise and I had a small “dip” around 7DPO but I got a BFN this morning with FRER 😢. I took one yesterday that showed a vvvfl but could’ve been an evap line. Am I out? 🥺
