Worried!!

Sarah
Ok so I'm from the uk so I know things are done differently in other parts of the world!! I have been super stressed out for about a week. Broke up with my partner and I'm 6 weeks 3 days today... All my pregnancy signs have gone totally... No bloating, no sore boobs/nips etc.... When I say stressed out I mean on a scale of 10 it's been a 12!!! This is my fourth pregnancy and normally by now I'm so poorly with sickness but I have nothing. Don't really know what to do!? Any advice please??
