hello bella's of Belly Belly

I have a question, and need some opinions

I have been TTC for 2 yrs now for bubba # 1, and had my 1st OI-IUI cycle. I was given the Pregnyl trigger on 28th March (saturday) and Inseminated on Sunday.

I know i was told not to use HPT as the Trigger will cause false positives. So i held out until 8DPO. I just wanted to see what it would be like to see 2 lines! hehe

So here is what happend:

8DPO = BFN
9DPO = maybe a hint of the faintest 2nd line ever! This got me curious
10DPO = Faint 2nd Line. No squinting needed. You can see it well, but light pink
11DPO = 2nd line appears straight away and almost same colour as control line
12DPO = 2nd line strong. Appeared instantly.

Is this still from the Trigger shot? Or is this really a BFP?

Today is 12DPO (14 days after Trigger). My blood test isnt until Next Wednesday

Any experiences & opinions needed. I dont want to get my hopes up

ps : All tests were done with First Response/Discover brand, and repeated with Pregnosis brand.

Thanks for listening/reading
