Hi guys me and my boyfriend Yamir have been together for 6 years

I'm scared that this may really be positive and he's gonna freak or he made it very clear that he does want kids but I'm in medical school and I really want to stay guys I can't have this baby right now , I'm sure that his mother is going to want me to convert to Islam guys I'm so stress what should I do ? 
 * up date guys * 
With great consideration we decided to let gods plan be what is at the moment , and to think best for our what have been child we would be able to give him\her the station or stability they would need , this deeply shocks me and him but god knows best and if we are blessed with a child thanks guy with love
