PZ - you sound so like us! my DF only has about 4% decent sperm, all the others swim backwards, have 2 heads etc, and are very slow at that! hence why we had 2 earlier losses. took 2 years to get our first son, we never used contraception after his birth and my AF came 28 days exactly after he was born, it took another 18 months before we got our surprise in feb this year, we weren't trying but if it happened we were ok, my boys are 2years and 3 months a part and yes it is HARD! but I love them both just the same, as I too thought I couldn't love another one as much as my first but you do! we also want 3 kids before 30 and I too have completed 4 years of uni and going back for another 2 starting next year, it is possible but not easy. We are waiting til our first is in school before we complete our family. Have a good talk with your man about it. Once your DD gets a bit older and things get a little easier I am sure you will change your mind
