Dr. Marc E. Lewis with Hillsboro Clinic in Hillsboro, Oregon, diagnosed my problem after going to Dr after Dr for years. I had been suffering from similar symptoms as you. All it took was a blood test to figure out my problem, which is I have a brain tumor that causes my prolactin levels to go through the roof. Hence, not being able to conceive. I am 40 yrs old pregnant with my fourth child. I hope this helps you somehow.
See an RE right away. Unfortunately time is not on your side. Hope you get answers and your baby soon. X
I also had that prolactin problem mentioned above. A pill a day fixed it. You can always go to Tijuana Mexico to a fertility clinic.
