BBT dropped - I think I’m out this month 😩😭

Erin • Wife & Mumma of 3 💕

I have stared BBT’ing again this month. I was hoping my temp stayed up, but unfortunately it’s dropped two days in a row. My chart when I fell pregnant with my daughter, showed a clear incline in temps. This time not so much!!! My hubby and I will now not line up in my fertile window, until April/May with him working FIFO week on, week off roster. Did anyone have a similar drop and still got their BFP?
