Oooh exciting!!!

FWIW - I've always used the crystal clear ones to test my pregnancies, and they were accurate from about 12DPO.

Good luck with your blood test (and congratulations!!)
I think First response is incompatible with my pee (tried 2 and later found out hat i was 2 months pregnant after a dr appt) and crystal clear worked.

Good luck on BFP!
