Thank you so much for your replies guys.

I did the cold drink thing and nothing happened but I felt two small kicks while trying to fall asleep.I know I should be reassured by that but I still feel anxious about it.I just can't relax, i was similar last pregnancy too.I keep thinking what if something is wrong, I hate that I can't see in to my belly and know that all is ok.
Hopefully after my u/s tomorrow I'll be reassured everything is ok.
