So this morning I got my BFP at 10 DPO. I tested with first morning urine.

My husband said the line was so faint that maybe the test didn't work right. So to prove to him it was a real positive, I took another test, at about 5 pm.

My question is, my test tonight is so much darker than this morning, so why?

I know its a good thing that it gets darker, that means more HCG is being produced. But that is a huge difference, especially for an evening test.

No rude comments please. Im new to this whole pregnancy thing!
