my fiancé and I. advice please

My fiance comes home Friday at midnight from being locked up for two yrs. I am so excited that I can't sleep. I know we are going to have sex seeing as it's been two years BUT... we live with my mom and her husband and until we can afford our own place I don't want another kid. I've told him and the look in his face looked like he was crushed inside. We have one child already and I've been raising her on my own for the past two years. Am I wrong for wanting this or ??? Keep in mind the sex is mind blowing and I won't take the pill because it gave me two periods in one month then I was younger and he won't wear a rubber. What do I do???
