Could Breast Augmentation Cause Elevated Prolactin Levels?

Hello, I'm 40yrs old and trying to get pregnant. I've had 2 miscarriages. One at 12wks and one a 6wks. My husband and I have been through a lot of testing at a fertility clinic and all abnormalities have been ruled out. The only thing is that my prolactin levels are very high. I've had and MRI and a pituitary tumor has been ruled out. I got a breast augmentation about 6yrs ago. I'd like to know if my elevated prolactin levels may be caused by the augmentation? Thanks
