I did a lot of thinking today, and DH and I talked again after dinner. I admit that part of the reason that we are not too keen on TTA is that we both hate barrier methods of BC and he refuses to pull out.

So we'd be back to abstinence and although we held off till we got engaged, well, let's just say that wouldn't work too well when we don't have an imperative reason.

But here was what I was thinking: Yes, I'm only 22 (23 in a month). And we'll have been married 2 years in Oct., so even if we got pregnant this week, we will have had 2 full years before Jr. shows up. And honestly it's not even the "us" that I am concerned about losing; it is the "me." KWIM? Logistically, financially, and emotionally, we are pretty well set to have a baby. And thankfully, you do get almost 9 months to get used to the idea. I mean, as set as you can be without having actually done it! But we do have the resources to pay for a homebirth, and my graduate program is online, and those kinds of things are "good to go."
So really, all of the reasons not to have a baby right now, for us, will never change. The fact that I won't even be able to go to the library unattended for 12 + years, or that date nights are limited by baby-sitters' availbilities, is the same whether we get pregnant now or in 3 years. And the wonderful parts about having a baby...to hear them say "I love you" for the first time or discover what their favorite color is...those are the same now or in 5 years, too.
In short, DH and I are continuing with the "eh" method of family planning. Which means that DH continues in blissful ignorance and I end up stressing the 2WW and being super conscious of what days we DTD during my fertile time. Oh well. I can't go back to not knowing about my body. Which is something that most days, I am happy about.
