Pregnancy Signs & Timing- Help!

Wondering what all you wonderful mamas out there noticed as your very first pregnancy symptoms and how soon you noticed them. Please throw some responses in these comments.

My husband and I have been trying for 5 months now. I am due to start my period in 3 days according to my chart and have had some strange things happening:

1) total exhaustion starting in the early afternoon through evening

2) feeling sick as soon as I start eating

3) strange cramping (feels like pms cramps)

4) “heavy” feeling when I pee in my uterus (best way I can describe it)

5) low back pain like I’ve never experienced before. Never had this kind of back pain before my period before.

6) very thick cervical mucus. I’ve never had this before my period so I have no idea if that’s normal.. usually I am considered “dry” this close to my period!

7) sudden feeling of being annoyed with everyone around me for no reason at all (my poor hubby. Currently I can’t stand how loud his breathing is 🙄)

I know that when you are trying it’s so difficult because every single feeling or sensation puts your mind on high alert. You want every single thing to be a pregnancy symptom so I am just curious how many women out there noticed similar things and just how soon you noticed them.
