I used to be so excited about kids

I used to be excited about having a baby, but the last time I thought I was pregnant everyone around me seamed to be ashamed and my husband was angry. So from then on I lost all excitement about being a mom and having a baby. Now my husband is telling me that when we get our house that he wants to have kids witch is in 5-6 months. I don't know how I feel about it because I'm not happy about it anymore. Now it scares me when he looks at me in 5-6 months and I don't want a baby. Everyone tells me I will change my mind but this last time really hurt me. I don't know what to do
