Melsie, what caused you to get the ultrasound that diagnosed the adenomyosis? How old are you? Were you having symptoms of adenomyosis? Everything that I've heard about adenomyosis is that it is very difficult to diagnose, especially from an ultrasound. The best way (aside from surgery) is to get an MRI. I had 3 miscarriages before I was diagnosed. The first baby implanted fine but I had a blood clot that caused me to lose the baby at 10 weeks. The other 2 miscarriages were doomed from the beginning. Probably because of my adenomyosis. I had a bunch of tests done to see why I might be losing my pregnancies. One was an HSG where they insert dye into the fallopian tubes and uterus to see if there are any abnormalities. My uterus was an odd shape, so my doctor ordered an MRI and that's how I was diagnosed. I got a second and then third opinion and all of the doctors agreed that I had adenomyosis based on my MRI scan. NONE of my doctors (and I've seen a LOT of them) were ever able to fully detect the adenomyosis on an ultrasound. So my first piece of advice is to take a deep breath and consider getting a second opinion and an MRI. My symptoms have always been mild. I have spotting in between periods and the first 2 days of my period are very crampy. Some women get diagnosed because their symptoms are horrible every day. What caused them to diagnose you?
If you do indeed have adenomyoisis, the good news is that yours is focal, meaning it is in one spot. Diffuse is a tougher kind because it is spread all over your uterus. I also have focal but was told that it is in a place where embryos like to implant. We'll never know why my 2nd and 3rd pregnancies weren't viable, but I do suspect they implanted near the adenomyoisis. I had a 4th loss, an ectopic pregnancy where I had my fallopian tube removed. I also suspect the adenomyosis damaged my tube causing the ectopic.
Here's the good news. At 37 years of age, I gave birth to a gorgeous girl. She turned 2 on Tuesday. Even with 1 tube and the adeno, I still was able to carry a child and she is as healthy as can be. (I did end up having her 6 weeks early, but I've been assured it wasn't because of the adeno). I didn't have time on my side. My first pregnancy was age 34. Hopefully you are younger.
I will also say that surgery isn't really an option for adenomyosis. I was seriously considering it with a leader in the field, but there isn't enough research linking surgery to remove adeno with increased chances of sustaining a pregnancy. They can never fully remove all of the adeno and it could cause uterine rupture once you are pregnant. You can try Lupron, which shuts down your hormones. The idea is to deactivate the adeno for a few months and then once you come off of the Lupron, try and get pregnant right away. I never did this treatment as I was older and Lupron puts you into temporary menopause. I was afraid I would never come out of the menopause!
The unfortunate thing is that not much is known about adenomyosis, so you aren't going to find a lot of literature about it. My losses could have been from the adeno or from the fact that I was older. Who knows? There are other women who never have a problem with their adeno and fertility. In fact, many women don't even know they have it until they are delivering a baby via C-section and are told that they have it. So that's good news. Finally, I just want to encourage you that chemicals and early losses are so incredibly common that just because you've had one, doesn't mean you'll never have a baby. Truly. I never thought I'd have one after my 4th loss, but only 4 months after that loss, I got pregnant with the child who is napping in the next room right now.
Try not to let this spin you out of control. It is a bump in the road right now. If there is any way for you to get an MRI or even another opinion, I highly encourage it. I'm not on this site much anymore, but I'll peek in from time to time to see if you've posted. I'm happy to answer any questions I can. There is hope. I think most of the women on this thread have had at least one baby. It is possible.
