I'm having a really hard time not thinking I'm pregnant. AF is 5 days late with no sign that she is visiting. I've taken 4 HPTs with nothing but a BFN. I think I would see a line but then it would go away. I'm trying really hard not get discouraged. With my first child I was 5 weeks when I finally got a BFP and it was a very faint BFP. Any words of advice or encouragement would do me some good...
