I have a dilemma regarding going to college and TTC

Me and Hubby just got married in February. We decided to start TTC. We already have a 5 year old daughter and a 12 month old daughter. We want to have one more at least, hopefully a boy. For personal reasons, we want them to be close in age. For one, it is because I do not work currently and just finished my diploma before my second daughter was born. I rather not go back to school or work and then take time off in the middle of my program.

So, I have decided to change my career to nursing. I just got the news that I got accepted into a 1 year long preparatory program. If I get high marks, they will accept me into the nursing program the following year.

Also, this was our first month of trying to make babe #3. I am already about 4 dpo. I am extremely happy to be able to go back to school but I am not sure what the best option would be.

I really want another baby and then go back to school but I don’t want to throw this opportunity away either. Should I stop TTC? If so, I do not think I will ever have another baby since school would take me about 3 years to finishes and by then I would be 28 wanting to build a career.
