Do you ever just want to scream when you see the posts that someone who has only been trying for a couple of months is pregnant?

It just frustrates me to no end! Me and my husband are going in for round 2 of testing tomorrow at the doctor (thank god for weekend hours). They didn't find anything on the ultrasound my first visit and when I started my period on Thursday, they wanted me back in for blood work and a hsg. Fingers crossed they can give me some news on what's wrong. I'm only 24, no family history of infertility, and I've got baby fever.
