This wait is just so annoying

I feel like this cycle I have done everything right. I managed to get a positive opk, BD at the right time. Confirmed ovulation with bbt.

Yesterday I had a dip in bbt , I don’t know what to think. I measure bbt orally, I thought maybe it was to cold in the room, but that shouldn’t affect an oral bbt.

Anyway, today bbt went back up. Could that have been an implantation dip? I know they are kinda of a myth... I tested today with a very cheap test (ordered from amazon, 3/5 reviews), it was BFN.

My period is due in 2 days and tomorrow I should receive my FRER order.

What do you think? Did anyone get a similar dip at 10-11DPO and still got their BFP?

I just hope and hope. 😔
