so sorry Polly, it's an awful disappointment, happened to me in March. Happened to ILGH last year too -- we're both now pg, if that helps? Just seems to take a lot more disappointment before the good egg comes along at our age.
Only thing I'm doing is lots of vitamins... took iron supplements (spatone or floradix both seem to work well) after MMC and chem preg, which helped me get my energy back, and as well as preconception vits, I also took an extra folic acid as I read somewhere you can get pretty depleted and it's essential for cell formation for the embryo -- no harm in taking extra, some women are prescribed more than ten times the standard 400 micrograms, so it does no harm, and might help.
The other thing that may be worth doing is seeing the GP, tell them about your early losses, as it means they'll take you seriously if you want them to run tests now would suggest Antiphospholipid Antibodies that's to test for sticky blood. From what I could find out, this is the main cause of recurrent mcs that they can do something about, ie give you low dose aspirin and possibly heparin too. It's worth the test if only to exclude it. Helped my confidence no end to rule it out.
Sorry you feel so awful just now, it really is a horrible feeling.
Big hugs for you and for Hippy. I read your trying again thread Hippy, so encouraging, sounds like you will go for it, and I'm hoping for the very very best for you that you get your good egg soon.
Personally I'm bricking it can't concentrate, can't stop crying, desperately want to hear good news tomorrow (12 week scan) and really worried that we won't........ Doing my very best to think positive, someone slap me and tell me to snap out of it, I know I'm really lucky to have got this far.
Jolls and Rainbow -- sticky vibes to you both.
