I'm probably going to get jumped on for being negative, but this really concerns me. Those tests are well known for giving blue lines within the time limit. I know. I had it happen to me over and over again. I wasn't pregnant. At all. Those are by far, the worst tests on the market, and unless you have a blazing, bright blue line, it's pretty hard to say they're positive.
I'm not trying to hurt you or bring you down, but I need to step in and say you really can't be 100% sure it's a BFP, because if you search the forums, or even use google, you'll find out how awful these tests really are.
I'm not going to come back to your thread again, because it breaks my heart to see you so excited over something that might not be anything.
Good luck, and I truly hope I'm wrong. You are such a wonderful, positive person, and I don't want to hurt you. Ultimately, however, either you're pregnant or you're not, regardless of what any test says.
Best wishes and I'll be praying for you!
