Is there something wrong here? I am 31 and don't have Children yet!?

My husband and I have been married for 7 yrs. I get a lot of pressure from my parents and friends to have children and they make me feel very guilty about it. I go to church on Sundays with my husband and feel like everyone is judging me. One lady ask me if I really loved my husband because I've been married for 7 yrs with no children and people ask me what I am waiting for? They ask me in such a condescending way, that it makes me feel like a whore that’s up to no good. My husband and I struggled financially early in our marriage. He worked for the United States Air Force and was only an Air man first class and we lived on base and lived with out furniture, money was always tight! I moved from Canada to the US to be with him, and couldn’t work because we were waiting on my visa card. 2 years later, I was able to help financially. He worked and went to full time school so he can get a land better career in the military. 2 yrs later, My husband got an honourable discharge because he had a disability but he still works for the military and now we are very financially stable.Then we moved because of his job. Then I fell into a huge depression never wanting to get out of bed, and never wanting to leave the house. I tried to work random jobs here and there but they were all dead end. I currently I have so many health issues, and on so medications. I'm not as happy and healthy as I use to be. When I got married my weight was 110pds and now I am 165pds at 5'0 in height. My knees hurt, I major stomach issues. I am not happy with myself I hate myself and my husband and I are having material problems. My clock is ticking, I would like to have children. Its really hard when people judge me and don't understand my situation. I have a nice house a little farm with goats, chicken, pigs and drive a nice vehicle. I've had a lot of setbacks in my life. I am not happy and people tell me I should be. what the **** is wrong with me. I'm 31yrs old and no children. Am I a bad person or wife person? People have made me feel so bad about myself I feel although I may not be worthy enough for anything or even a child!
