I Have Just Completed My Infertility Work Up. I Have

I have just completed my infertility work up. I have four children. I recently had two miscarriages. I am 41 years old. All test look great with my hormones, his sperm count, no genetic issues. My FSH is 6 and I have 19 follicles. I got pregnant in Feb and Mar but then waited to try again for my testing. What are my chances of having a baby? I don't smoke, drink, do drugs and live a healthy lifestyle. I have always had an issue carrying a baby but never had an issue conceiving and still don't. I have a weakened cervix.
