I know its wrong to be a little jealous but.....?

I find my stomach sinking when woman after woman announce their pregnancy! :/ I know that in due time it will happen for me and everything but its just happening for everyone else a little easier. And it doesn't help that my husband and I can't try for the next 3 months while he's out of town....geez! It seems like pregnancy is spreading faster than the swine flu and I can't seem to catch it (pregnancy that is...not swine flu) But all other women have to do is LOOK at a man (husband/boyfriend or not) and he gets her pregnant! But that will all change in 3 months hopefully when my hubby gets home :) But does anyone else feel this way sometimes?
