Sadly MC rate does rise steeply as you get older - even from around 35, and by the early 40's it's about 50% or more.
That DOES NOT mean you are too old, or shouldn't try, and there are things you can do to reduce your chances of conceving a genetically unviable pregnancy (one which sadly just can't survive.
I think you need to be strong, and have a realistic view, and accept that you may have several losses before you get your baby.
I found my first mc at age 40 devastating (she stopped developing at 12 weeks), and went on to have several more losses between 4 and 9 weeks, about every 3rd month for 18 months (they were easier to handle as we had accepted we were doing something high risk), before I fell pregnant with a viable baby (he's due in 2 weeks, 2 days, and I am approaching my 43 birthday soon!).
We had genetic testing done on one of the m/c which showed an unusual trisomy, and my consultant told us older eggs often fail to divide properly due to either lack of folic acid or incorrect metabolism of folic acid, and this is a cause of rising rates of MC in older women (your body can't procces it as well as you get older), and he put me on a high dose suplement (5mg per day- more than 10 times the usual dose for non pregnant adults) of folic acid, and instructions to take mini asprin from the day I got a positive pregnancy test (to help the placenta embed and function). For me, it's worked!
It may be worth asking about both those supplemnets, though I think some consultants are less keen than others to encourage "old" women to keep trying (though tbh it's the midwives I found to be very judgemental with comments such as "you can't keep doing this" (because THEY said THEY didn't want to see me going through yet another m/c!), where as the Doctors were very much "if you feel able to keep trying theres no medical reason why you shouldn't").
Other things I was advised - daily multiviamin and pharmacutical grade fish oil (that's the expensive kind of course, as it reduces inflamation in the body), no Caffine (it reduces rates of conception), no pain killers (paracetamol is ok but not asprin or Ibuprofen) at around the time of ovulation, as they can cause the ripe folical to turn into a cyst instead of bursting to expel the egg - which means no chance of fertilisation. I found that one hard, as the older I get, the more ovulation pain I get, but I didn't take anything, not even Paracetamol.
I hope you find at least some of that information usefull. Maybe I will get flamed by some for pointing out the negatives, but ignoring the risks isn't sensible, knowing the risks, accepting them and doing what you can to reduce them is very sensible, and may help you get where you want to be

Good luck it you decide to try again.
