I have had the AMH test done and it came back "extremely low". Which made me feel a bit sad at the time. However, since having that test I have conceived three times, sadly none of them stuck, but they were at age 44 and 45, so not surprising.
So, the amh test has basically told me that I don't have many eggs left, but it really doesn't make a lot of difference to me, I have continued to ttc anyway.
I had the test done as I was going to see a fertility specialist. I changed my mind as I knew he would suggest donor egg and I didn't want to go down that road.
Since having that AMH test 2 years ago I have ovulated every month (I track it with charting), so low reserve doesn't necessarily mean your time is up.
Incidentally, my DH had a reversal (after 7 years), and we got pregnant 7 months later with our DS, who is almost 5. He was conceived around my 41st birthday. Who knows, if I'd had my AMH tested then, it may have been just as low?
I did a lot of research after getting my "extremely low egg reserve" diagnosis, and found that many women get pregnant and have babies after that diagnosis.
I still hold on to the hope that there may be just one golden egg left and I will catch it one day.
I think if I were you I'd get the reversal done asap as once it is done, if it is successful, you will have every month to have a chance at ttc, whereas if you take the assisted route you won't have as many opportunities and I'm guessing it will be expensive.
I wish you all the best.
I wish my DH had had his reversal earlier so that I could have been younger, ttc at my age is a battle.
