Hi mrsr so sorry to hear about your miscarriage. And so awful to get to the scan and find out your little pea had died :(
Cramps and brow spotting are, as your mw said, quite normal. And don't necessarily mean bad things or were linked to the loss of your baby.
Re high risk status. Can I ask if they took the baby away for any tests? If they did this might conclude something that could mean you were monitored more closely in early pregnancy to check things are ok with scans etc. but shouldn't mean you can't give the MW led unit a whirl. It all depends on what your next pregnancy is like.
I've had two mcs and still allowed to use the mw led unit of all is ok and I want too (I have a child already which was a difficult birth and that is the only reason, not the miscarriages, for why I wouldn't be allowed to use the mw led unit is if it's in the wrong position or I require induction or a long labour when I will need a c section)
And you can request an early scan but not all areas give you one as standard after a miscarriage. But you can pay for them ranging between about £50 and £100. But if there were identified complications with the baby you lost, they might do earlier testing with your next pregnancy. I had 4 scans in the first trimester - one I paid for, three by NHS. But their reasoning was suspected ectopic and miscarriage history.
Hope that answers your questions to some sort of degree of helpfulness! When you are ready to start trying again (please let yourself grieve this one and give yourself time to heal) the ttc after miscarriage thread - posifrickintivity one is great for people dealing with the awfulness after miscarriage and trying to get pregnant after mc. Here we support each other through the scary of being pregnant after miscarriage.
Also, you can't really stop a miscarriage no once it's happening - but worth getting tjjjngs check out once you are about six weeks as those symptoms can also turn out to be nothing and there is a healthy growing bean in there!
