HMommy So sorry to hear about your losses.
I am 42, have one DS (3 years) and have just had my 4th miscarriage. Also very much all over the place at the moment...
It is truly heartbreaking, especially if they can't give you a reason why this happens. I have no problems falling pg, but can't seem to stay pg.
Age is of course a factor, but then again, so many women have healthy pregnancies and babies in their forties! Like you, I had aspiring, progesterone and also heparin during my last pregnancy, but I still lost it. Now waiting for the test results, hoping that it might give us a clue.
We also had tests after the mc before this one, but all they could find was a spontaneous mutation in the baby, no issues with me or DH.
Have you been tested for blood clotting issues? This can be an underlying issue that might not cause any problems for yourself, but can make it difficult when you are pg. I would ask your GP or hospital for the tests, if you can face it.
It is such an awful situation to be in - I am struggling with the thought that DS might stay an only child, and am currently thinking about what options I have. I will look into the immune-issues/NK cell testing, as this seems to be the one thing that I haven't tried, apart from fertility treatment - for which I'm not sure I'm up for anyway, I can't see how it could help me. And then I am -tentatively- thinking about adoption...
As you can see, you are not alone! Be kind to yourself, take one day at a time until you feel more robust... It is a roller coaster, and a very bumpy one.
