Sigh*... It happens...usually around the time I ovulate. I get such in a depressed funk - it's hard to get out of. It does not help that everywhere I look, people seem to be pregnant or just had a baby! What is it with that?!!! I can also find for you every reason why this seems to be unfair as well! I just found out yesterday that someone I know is pregnant with their fifth child...FIFTH! - and their youngest is only 12 months old!...is it a blood competition or something!
