Sounds very promising! Within the next couple of days, that line should start getting darker. Once it is nice and dark, that's when I'd go to the doctor's to explain that you think your pg because of you've had BFPs on the home pregnancy tests that you've used. I'd take one with you! Then ask for a blood test to confirm the pregnancy and if you can have a dating scan.

Good luck and a mini congratulations for now! Wishing you
