Hi Victoria,

I've heard that the Clear Blue digital are less sensitive than the First Response. The First Response Early Pregnancy Test are very sensitive.

Do you know when you O'd? Are you charting? It is possible that you have O'd later this cycle and are still testing a little too early. I got my BFP at 17DPO (still a BFN at 15DPO). If I were you I would wait 48 hours and then test again with the First Response Early Pregnancy Test and use FMU. (HCG doubles every 48 hours.)

Good luck - I hope its a for you!
