Having a baby in grad school? Anyone done it?

I'm not pregnant, I've been TTC over a year and recently learned from my doctor that I may never get pregnant without fertility treatments. The thing is... in the time we've been TTC I didn't put my life on hold. After six months of no success, I applied to and was accepted to a masters program and was offered a teaching job at the university to support me through the program. Dream come true! So I started that this Fall. It's been pretty crazy being a grad student and first time teacher (I teach a class 5 days a week and create my own lessons and assignments and tests and everything) but I'm pulling through. And we've been TTC through it all, 15 failed cycles, now working with a fertility clinic. I always thought if it happened, it would be meant asto be, and I'd try to be the best mom, student, and teacher I could be. But now I find out I need seriously help to conceive. Now it's not just having sex. Now it's meds and procedures. My doc recommends IVF even as soon we're ready. And that's a whole different thing. This would be so extremely purposefully getting pregnant in the middle of a grad degree. If we go ahead with our treatment plan for this month and next and got pregnant, I'd have a baby right before my second (and final) year of the program. It would be a year of intense juggling. Should I do it? Or is this being irresponsible?? I'm 2 months shy of 26, so not terribly old, but we want a few kids and we to start soon and waiting a whole year to get pregnant sounds awful! But I don't want to be a bad mom and a bad student, trying to do it all and fail. Anyone been here? Any thoughts?
