That's it really. I am 5 weeks pregnant (plus four days), with absolutely no symptoms. I have had three previous pregnancies, in two felt I very sick, almost immediately. One other was not so bad, but I definitely felt pregnant. As far as I can remember. I'm quite old (43) now so know that chances of miscarriage are high. And I'm going on holiday for two weeks on Monday. I feel sure that this must be a missed miscarriage or something (in between obsessing that this is twins, the thought of which is also making me feel ill with anxiety). Is it worth getting a viability scan? Or should I just wait and see?
