TTC-I am going crazy!

Hello, so my husband and I are trying to get pregnant. I was supposed to get my period at the latest by today, but I havent so far. I usually starts a couple days early or right on time...almost never late. If I am late, I usually spot. I have not spotted at all. I have been experiencing some symptoms that are not what I normally have for my period. A couple co-workers of mine think that I am pregant. One because of how I am acting, the other "just has a feeling". I know some of you have probably been "studying" pregnancy tests longer than me, so maybe someone can help. So looking at these photos, does anyone see any sort of line on any. I swear I see a line, but I feel like it might be my mind playing tricks on me.
