Cold Uterus

Has anyone been diagnosed with a cold uterus? I googled it on my own as being my abdominal area always feels cold. I have had 2 mc in my life and 2 chemical pregnancies. I am starting to think this might be the cause. Anyone have any advice or suggestions?? Please I'm 38 and my ob told me to go see a specialist. I guess because of my age she thinks I should do invitro. That's not an option financially so I'm looking for natural ways to get pregnant and then I'll make sure my ob keeps me that way.
