Love:
I'm SO sorry you are having such a rough time. Seeing all of the preggos, pg announcements, ultrasounds, and also hearing about your friend's birth is making this TTC stuff so much harder for you.
Are you sure that you won't have time for at least one or two BD before he leaves that will possibly be in your fertile window?
I know what it's like to feel like you are in this alone, and that your DH doesn't care as much as you (mine said he'd be fine with never having kids, even after going through the m/c with me in 2000 -- it hurts).
I know your doctor told him to cut back on the energy drinks and smoking (I think mine avoids BD now since I'm on the Clomid) and I don't blame you for being upset with him. But he can't stop a BFP -- look at all the people who smoke and drink and still have babies! They're everywhere! My coworker told me his wife smoked the whole time she was pg (which makes me SO angry btw, since I had a m/c and did everything right). My mom is right about one thing; this is what she told me one time when I was upset: "I don't care if you only have sex ONCE a month. If you aren't using protection, you are going to get pregnant." And I don't know anyone who tried and tried to get PG and never did (I hear all kinds of stories about so-and-so who tried and tried and DID get pg) but never anyone who wasn't successful.
But if you want to take a break from actively TTC and NTNP for a while, if it will help you, then do it. A lot of people say when they stopped trying, that's when it happened. The truth is, no matter how much we obsess and plan and test, it is one of life's mysteries. But people have been having babies for eons; our bodies are built for conception! I really think it will happen for all of us.
Chris: I know what you mean about being angry and feeling old! I told DH I'm mad that he made me take pills throughout my fertile 20s -- but my doctor said he couldn't "make" me and I did have a choice; I guess she's right but I keep blaming him anyway LOL!
