Increased sex drive last trimester???

Aleia
Ok I have to admit this is a little weird, but I have to ask, am I the only one who has an increased sex drive in the end of pregnancy? Do you think it could mean my body is wanting to help the process along?
I've heard how the second trimester hormones can cause a woman to want to be more intimate and/or sexual with her husband or significant other. However I feel like it waited until this last stretch to hit me! First trimester I felt like I was hung over all the time (no use of alcohol even before we conceived) second trimester I felt like my whole body was PO'd because of the pregnancy and I hurt way too much from growing pains. Third trimester hits and bam!!! I'm a horn dog!! Yes I'm very pregnant, feel like a beached whale, very uncomfortable, but this urge blind sides me out of left field.
My dr said He doesn't see me making it to my date in 17 days because I'm 90% effaced and 2cm dialated. Could this crazy phenomenon be my bodies way of saying that I am super close, and trying to help jump start the process?
