prolactin levels

Ca
Do any of you have low prolactin levels in your first trimester? I went to the doctor to do a blood test for pregnancy and instead of my doctor check in my hCG levels she check my prolactin. If you don't know what prolactin is it is a hormone in your body that helps your breast produce milk for your upcoming baby. She said even though I have all of the signs and symptoms of being pregnant my prolactin level is too low at 7.7. she is now thinking that I have either a fire right issue which she also checked for blood that came back negative or I have PCOS which was ruled out three years ago by my OB/GYN in my other state . I tried to explain to her that my hormone levels are fluctuating a lot and that even my progesterone was quite low. When I went to my OB/GYN who specializes in fertility she told me that my hormones were completely out of whack and my progesterone was so low that if I don't get pregnant I would have to go on supplements right away. Have any of you ever dealt with a doctor that just doesn't want to believe that you're pregnant and is not going by hCG levels to see if you are pregnant or have any of you guys ever had low prolactin levels in your first trimester. I would really appreciate any type of information or experience that you guys of had with this honestly I just moved to another state I'm doing with a completely different doctor and I'm just very upset and confused and she's trying to make me think that I don't have a baby now and I know that I'm pregnant. Thanks ahead of time for any of your help!!!
