I'll be honest, it'll be easier for you to finish uni without having a baby to look after. That's not to say it can't be done, it can, balloon_parade is a testament to that, but it's easier without, naturally.
I personally started uni in Sept 2004, got pregnant in Jan 2005, finished first year in Summer 2005, had baby in Sept 2005.
Took that year off then from uni, and went back to uni in Sept 2006 in first year of a new course, when my daughter was a year old.
Then...
got pregnant in Nov 2006, finished first year of new course Summer 2007, had baby in August 2007.
Took the following year off from uni, and went back into 2nd year of new course in September 2008 (when my daughter was 3 and my son was 13 months old).
I lasted until the beginning of November 2008 and then quit uni completely. I just couldn't cope. My son was extremely clingy and he wailed the place down when I had to go to lectures, and was totally unconsolable until I returned. He's still a little clingy now if I'm honest, and he's nearly 5 years old now!
If it had just been my daughter though, I think I would have managed. As I say, balloon_parade has done uni with 2 children. Other people find that even 1 child is too much to cope with whilst studying. It really varies, you can't predict how these things are going to turn out.
One piece of advice that I will give you though, is that if you do go ahead with TTC whilst at uni, I think it's a little ambitious to expect that you'll be ready to go back to uni when your baby is only 5 months old. I'd be looking at taking the year off if I were you and going back when your child is a toddler and a little more independent.
At the end of the day it's your choice. It can be done if you're very very organised, but if it were me I'd wait until after uni. I regret not having been able to finish my degree, though obviously I wouldn't change my life as I love my kids, but if I could have had my cake and eaten it too, I would have done my degree and THEN had kids. Hindsight is a marvellous thing. (I went on to have a third child in Sept 2009 as well, but my uni days were obviously a distant memory by that point!)
