I am about 5w2d under my calculations. A week ago I took one of those CB tests with weeks estimators and it said 2-3 weeks. Today I expected it to say 3 weeks + given it had been a week but it didn't. Now I'm freaking out that my hCG isn't doubling.

Just looking to see if anyone has any experience with this and if you found them to be accurate? I may have to call my OB and ask for an hCG if tomorrow's test still doesn't go up, just to alleviate anxiety or find out the bad news.
