in need of some advice

I secretly want to have a second baby. My 1st is 2yrs old. My 1st pregnacy was high risk and I had a traumatic birth experience and because of it developed postpartum depression and anxiety. I feel that I am ready and overcame those issues. The problem is that hubby is not ready for a second.. I feel that he is scared or uneasy that I might get sick again.I am not on birth control but my husband is very on top of it when it comes to the pull out method. Do u guys think I should wait until he is ready or should I secretly per say find a way to get pregnant? I just need some advice.
