Mrsr - I still experience those bouts of rampert hormones now! I find it gets worse when i am over tired or feeling rather exhausted... But i too cried at work (when i worked) during early pregnancy, i would just burst into tears over nothing at all!

A cuddle always helps me but i think you will find in a few weeks you will have gained some energy and won't feel so drained and tired all the time and you will feel you are able to cope emotionally better and start enjoying pregnancy.
