Feeling reeealy weird?

[TTC No1 in August]

AF is due tomo, and we BD on the 2nd & 3rd August, and 2 days later on the 5th I had normal mid month very light spotting that I normally get around ovulation.

Over the last few days I've had a few odd light cramps in my belly, and I've been feeling Really light headed and dizzy, which is something I never get.

This morning whilst walking through town my head felt like it was drunk, it felt like I was swerving as I walked.

This afternoon back home I feel incredibly weird. Normally before AF I get grouchy/angry/tearful, but I just feel odd. Totally spaced out. Hubby has also said the last few days my skins been hot to touch, and on and off I've had odd pains in the tops of my thighs.

This afternoon I feel a little nauses.

So my questions are as follows:

1. Could this spaced out feeling be an indicator that I'm preggo?

2. If it is preg related feelin sick why am I getting it mid afternoon and not when I woke up this morning?

3. Do you feel hotter than normal when you early preg?

4.Am I comin down with flu or something!!!!! lol

I know none of you are mind readers, I just ask for your valued opinions.

Thanks

Em
