Feeling a bit worried

So at 19dpo I used my last IC and was happy to see a nice progression and dark line. I was left with only opk's which I used of course and had nice positives.....until today....I really hope my urine was dilute. That opk was not positive. So of course I run out to the store for more hpt's. Pee'd again and did the test. It's pretty light. Much lighter than I would expect for 22dpo. Bbs are still sore but not quite as sore as even this morning.....:(.....I am going to try for a good hold and do the other test....maybe tonight or in the morning. Beta is tomorrow but I won't hear anything till the weekend. I just don't get it at all....I was in the freaking acceptance mode when I got this bfp. If I lose this one I have to get there all over again. Seriously I said it before and I'll say it again I would rather a bfn then to get my hopes up then m/c later....it's some kind of cruel joke that's for sure.
