So, I added my story in another thread. Following 2 pretty horrendous miscarriages (I suppose they all are to be fair) I am pregnant again - currently 8 weeks, with a heartbeat on my scan at 7 weeks 5. The first Pregnancy never developed and the last pregnancy had a heartbeat at 6 weeks 3, my 8 week scan then showed no growth from 6 weeks 3, and baby had bradycardia. Wind forward another 2 weeks, the little heartbeat was gone 
The positive from that, is 7 weeks 5 days and still going strong is my furthest yet!
I decided after my last miscarriage that I do not give a monkeys. I will be having weekly scans from 6 weeks this time round thank you very much. This ended up being from 5 weeks to rule out ectopic so I could continue on progesterone.
All my research has told me scans can't harm babies, but it does seem more like "there's no evidence a scan could hurt" as opposed to "there's evidence is doesn't".
I was 100% invested in the concept of weekly scans, for many reasons, the strongest of which is they really help with my anxiety for 2 reasons. 1 - they give me weekly milestones, a week goes relatively quickly and gives me something imminent to work towards. 2 - if something is wrong, I want to know now. Miscarriages can be hideously protracted and you likely have to wait a week or two for a second affirmation on the NHS. If something terrible happened again, I'd prefer to know sooner rather than later.
Last scan, the sonographer told me not to have too many scans as whilst there's no evidence, it may harm the baby.
Does anyone have any knowledge on this that they could share, any sonographers here?
The key for me is whether multiple scans, or the crippling fear / anxiety of losing this baby too will be worse?
