kitty so sorry to hear about you prolonged limbo. I really hope that they see you tomorrow and you are not kept lingering over the weekend. At least with an amnio you will Know 100% if there is a problem, not just be given a risk which frankly is meaningless.
worry pregnancy is a worrying time, and for most of human history has been really dangerous. In fact it still is for most women alive today. It's natural to be worried. Do you have a named midwife to speak to? I think you said earlier that you didn't. My last pregnancy was awful. I'm a low level worrier anyway, but my anxiety was off the wall. I was at EPU or maternity triage most weeks with some concern or another (too much discharge, not enough discharge, feeling very sick, not feeling pregnant, odd foetal movements, no foetal movements). Eventually someone twigged and I was referred to their women's psychology service. It didn't help much, but did give me an outlet. This time round things have changed, and I actually have a named midwife who coordinates my care and is available to either call or text or email more or less any time. It's made a big difference. DS1 had chicken pox, and was anxious about my immunity. The GP was concerned but it was going to take ages to get blood taken and results back. I called my MW and she got is all organised there an then. I really hope you get it sorted.
So, 12 weeks today and my nausea has all but gone. I've got some energy back. Spent today cleaning my car and cooking for DS1's birthday party. Slightly regretting "tidying" the millionaires' shortbread by eating all the wonky bits.
