I'm so sorry @TheBirdintheCave. It is absolutely not fair at all.
With regards to the two MMC- this is what happened to me, two in a row, and every doctor put it down to bad luck. This is horrible to hear though, as you feel powerless. I did go to a private gynaecologist after the second one as I wanted to just do something and he prescribed aspirin from BFP and progesterone, even though all my tests came back clear for clotting disorders. Who knows if it made a difference but it certainly did to my mindset.
Also, my second MMC was found at 9 weeks with no development beyond 7w4d. I opted for medical management at home. I actually found it far easier than the first, maybe because I knew what to expect, who knows. I got codeine from the hospital which may have helped, and I could plan exactly when to take the pills. I saw absolutely nothing. I think at this stage they are still super tiny ❤️
