I have recently had two chemical pregnancies back to back. I also was diagnosed with hypothyroidism after having my daughter in 2011 and am currently taking synthroid. We are trying to figure why I miscarried in the same manner back to back. I researched and found that high prolactin levels, hypothyroidism, and miscarriages are linked. I have signs of having high prolactin levels........I've been able to express milk STILLfrom my nipples when squeezed. I quit breastfeeding 14mo ago. Today I had my prolactin levels tested today and am currently waiting for results. My question is could I be right in thinking my levels are high and causing me to miscarry early. So far everything ckd out. Thyroid levels are fine and so is my progesterone.
