Oh I remember those days of wondering and noticing every single little detail and thinking "is it pregnancy related???" but many times it was not and was just my imagination.
I might as well be talking to a wall, because I remember how impossible it was to just wait without thinking about it, but I encourage you to try not to pay attention to the little things as the disappointment is very difficult to deal with when it turns out to be just normal bodily functions rather than pg. Even now I feel so many things that I realize are similar to pg that its no wonder we experience so many symptoms and attribute them falsely to pg!
With that said, I did get a cold during the 2WW of my first child and I had no idea it was pg related. It wasn't a true cold, but a serious stuffiness although I had no idea it was actually a pregnancy. I had weird swelling immediately after conception with my 2nd, and I can't remember anything significant with my 3rd (he was my 4th pregnancy within 6 months so I was pretty desensitized to getting excited or paying attention to the little details as I couldn't seem to stay pregnant).
Try to relax and know that God will give you that perfect child when you are meant to have him/her! My son is a perfect example, if any of my previous miscarriages had turned into a child, I would not have my son and I can't imagine life without him :)
