I also have DOR. It means simply that you are getting low on eggs but doesn't mean you can't get pregnant with your own eggs. If you do IVF, you will likely not get as many eggs as other women of your age without DOR. Since it only takes one to get pregnant, please don't think you are doomed to using donor eggs. You are still young and your age is in your favor. I'm older than you and also a fragile X carrier so I will be moving on to donor egg. I have seen plenty of women on this forum in their 30's get pregnant with diminished ovarian reserve.
DOR does cause FSH levels to be higher but they can also be low and your estradiol levels can be high. My last FSH was 5.2 but estradiol was 88. Having estradiol too high means that your ovaries are recruiting earlier (before you even get AF) so by day 3 the estradiol is higher than it would normally be. Some people ovulate early because of this. They usually also look at your antral follicle counts and can tell if you have DOR by how many follicles you have early in your cycle. Here is a link that has a lot of good info on it.

Good luck to you. I'd be happy to answer any more questions you have.
