Hello. Firstly I'm so sorry for your loss.
I'm now pregnant for the 4th time after suffering 3 miscarriages in a row. I had my 12 week scan this week and all being well everything is ok.
However I have been in your situation 3 times and I know the pain and grief you are going through and trust me it doesn't get any easier with each attempt.
My advice, honestly? Give yourself time to grieve. I know that desperate knee jerk reaction to be pregnant again. I really do. I was told by doctors to wait at least until after your first period. It seems like a lifetime, but it's not.
Lots of people will tell you, don't worry about it, TTC straight away. There's nothing wrong with it.
It's true, if you fall pregnant without a period in the middle you will not do yourself or your baby any harm.
However - when you don't have a period first, you have no starting point as you have no last period date.
So if you have an early scan, which is quite likely after an mc - it's very difficult to date the pregnancy and it could be you are perhaps not further along than you thought or sadly things are going wrong again.
I've seen the distress of those people far too many times. Don't put yourself through it. It's awful.
If you wait until your first period. You've rebalanced your body, plus up need to recover and grieve. Be kind to yourself.
This is my 4th pregnancy and I genuinely never thought I'd get to a 12 wk scan. But I have.
Just take a deep breath, grieve and look after yourself and try and wait until after your first period. It's a fresh start.
I know it's agony and I'm sorry. My 3 mc's were the darkest 9 months of my life - my. 3rd mc was 3 weeks before my 1st due date and I thought my world was ending. Been through my 2nd due date since then and still got a 3rd one to go
Big hugs
