As PP has said, AMH is a measure of egg reserve, it's of no indication of whether you'll have another miscarriage. High reserve and quality can go hand in hand, though, as the more eggs you have, the higher the quality of the eggs tends to be. Both of these numbers decline with age.
I've had a handful of miscarriages all in a row, I've never had a pregnancy go to term. My last miscarriage was November last year, but it was an IVF pregnancy, on a high amount of hormones and it was an empty sac measuring 5w3d. It took months to resolve.
Now I'm currently 5w3d (funny that!) into a complete fluke pregnancy. I have no idea if it'll progress, but I'm taking each day as it comes. All my losses were early, before 6 weeks, so I'm absolutely terrified. But all I can do it sit tight and put my mind on other things.
At this stage, don't test your AMH, but do keep testing your hCG to ensure it goes negative. You can then try to conceive again as soon as you're ready. Bear in mind that every loss is different, so you may be better waiting until your cycles get back to normal first before trying again.
My cycles weren't wonky, but they were very heavy bleeds, as in little to no progesterone, so my body just dumped out the lining in a day or two, I flooded and couldn't leave the house, so there was no way a fertilised egg will have stuck.
