Thanks for all the replies. I do feel reassured but still had a terrible nights sleep waking up to check for the pains : but they do seem to have eased off a bit now, although i have also convinced myself that my boobs dont guet anymore! Lower back ache is definitely muscular but it is quite misleading and does freak me out a bit.
Unfortunately I am not in UK and we don't have an epu. I had early scans on NHS with DS for such small reasons in comparison. It's all private here but you do get subsidised maternity care, but they have a no scan before 7/8wk policy unless they really suspect ectopic or dates are a real issue. And even after 8wks you'd have to be bleeding or doubled over in pain.
I could pay £100 for one but I'd like to wait a week or so to make sure I had a chance of seeing a heartbeat - if I was too early and nothing there I would freak even more.
Really nice to hear some of you have had some positive early scans over the last few days.. It's reassuring despite obviously having zero to do with my pregnancy!
While writing this I have had a few twinges really low down in my pelvis but I think they do feel more how I'd expect pulling and stretching to feel so not too worried about that.
DH has taken DS out and while its nice to be alone, I'm really struggling to drag mysel up and stop worrying. I have wallowed for about 24hrs and I can't seem to get on with anything. It's all consuming, this worry, and I don't know to switch off.
