A sixth sense on fertility

Does anyone else have this ability that I seem to have where I can sense when a 1)woman is pregnant,2) trying to conceive, 3)or is going to have a hard time conceiving/infertile ? 
I have been right thus far with my friends, associates, and co-workers.
It's almost like a vibe or scent they give off. Sometimes it's the body type of the woman and the way she is carrying herself. 
Does anyone else have this ability? I'm not saying it's special, I just feel in tune with the things people transmit in their daily lives.
