I have also noticed my veins are more obvious, while i thought that was a sign for me but I noticed my little sister (17) has the same thing at the moment due to the extremely hot weather.

I have no syptoms as yet, the cramping i had last week (AF not due till end of this week). I expect to get sore boobs later this week as on my last preg I noticed this after AF was due.
