So....my husband and I had unprotected sex a couple weeks ago. My period was due yesterday (Thursday), and it didn't start. Maybe this is paranoia, but I went ahead and took a pregnancy test this morning, first thing, since the hormones are obviously more concentrated then. It was negative. I've heard about false negatives with pregnancy tests, but that's usually BEFORE the period is due, right? But then I started thinking about the fact that when I was pregnant before (and had an early miscarriage), I tested TWO WEEKS after my missed period, and the test still showed a very faint line, indicating low(er) levels of hormone. Is it possible that my body/my embryos just don't produce much HCG and take much longer than average to even show up on a HPT?

I'm really worried here. Not that it would be horrible if I got pregnant again, but I took the miscarriage pretty hard, and I'm afraid I'd be a nervous wreck the entire pregnancy, worried about having another one.

I just wanted to know if any other women have experienced this--a negative result on the day of, or after their missed period, that was later shown to be false. And at what point did the positive finally show up? Thanks so much for your input.
