Not sure if your dr will think your weird, but.

This time last year, I had a BFN, then for some reason on Xmas eve, I bought a test, tested on Xmas morning, with a very clear BFP in about 10 secs.. But I have no idea how many DPO I was cause my cycle was changing each month.

So it is possible.. But maybe your dr will give you a referral slip to get done if you still think you could be pg next week (save going back, just for the slip).

Good luck. Hope it is a BFP for you
