Hiya, so sorry for your loss xx I too have just finished having a miscarriage also should have been 8 weeks but passed at 6 weeks, so very similar to you.
This was my second miscarriage my first was at 6 weeks 3 years ago before having my toddler, the two experiences couldn't be more different, First time round was immense pain with such heavy bleeding a few days later lasting around 5 days. This time I had a scan heartbeat was seen but measuring small so I knew deep down it probably wasn't meant to be, I'd been experiencing spotting leading up to the scan then the very next day the bleeding got much heavier like first day of a period but never soaking a pad and no pain whatsoever which lasted for a week before hospital confirmed pregnancy had passed.
I remember first time round despite the pain I dusted myself down a lot quicker and actually we conceived the next month no period in between. I was emotionally distraught initially but processed it quickly.
This time because i was expecting it I didn't cry at the hospital (i did tear up a little last werk), took the information In and have told everyone I'm absolutely fine which I do feel I am, before this my energy levels too were high I was feeling OK. Today however it has hit me like a truck , I am not so emotional but I feel exhausted, tired, headachy, I haven't yet bothered testing but imagine I will be negative in the next few days if not already.
I am not sure If maybe it is because I am now older or running around after a little one . .or maybe the not as physically painful miscarriages perhaps are a lot more detrimental to us after whereas first time I went through it all with the pain at the time?
Hopefully in time you will feel more like yourself again, all the best xx
