No one to talk to and getting down... (24 yr's old)

Lorena • Married since 11-30-13. TTC since May. Baby dust, please!
I have been married for 10 months and I totally love my husband. I'm very active in our local church (where I met my husband) and we are the children's church leaders. We have been trying for a baby since May, but no such luck and I'm really scared. My maid of honor and her husband live down the street from us, but they don't really want kids right now, so she doesn't understand. And my husband's good friend and coworker lives right next door... And they are having a baby. And all she does is complain about being pregant. I totally get that it's hard to go through pregnancy. But at this point I'm just frustrated and upset. I don't have any other friends and my husband doesn't understand.
​My period was always irregular before I got married, then it got regular after we got married. But since April/June I have been like 21 days late each month and now I am three weeks late and negative tests... I know I need to go to the Dr., but my husband was sick for a month and his bills are somewhat expensive and I don't want to add to that right now. I just need someone to talk who might be going through the same thing.
