So apparently the "hook effect" is a thing. I remember reading about it during our first pregnancy, but as our first appointment was earlier, I never tested this late. I tested this morning (6w5d) and the line was WAY lighter than the control, and way lighter than the previous tests. CUE HYSTERIA.
I did some googling, and apparently the hook effect is a real thing. I don't have anymore tests to do any diluting, but I may buy some this afternoon, just to ease my pounding heart. I've felt better after googling, but whew. Must it all be terrifying?
Edit: Probably just sent my husband to the store to get me some tests so that I can try diluting the urine. It's silly to keep testing this late, I know, and I'm just causing myself more anxiety, but seriously, this is the first time I've been anxious in 6.5 weeks, so I'm just going to go with it and make myself feel better about this one.
