Prayers please- is anyone else in a similar situation?

Hi All! My husband and I have been married for almost 2 years (July 11). I have a daughter (she's 16) from a prior relationship. Our family has blended well but my hubby and I would like to have a child (he has never had his own kids). He's 35 and I'm 34. We've been TTC for a year now with no success. We are praying that we get pregnant soon....or in God's timing. 
It can get frustrating though because people ask me if I'm pregnant (I'm small framed so I don't actually look pregnant) or ask us when we'll have kids....and they have no clue to what we're going through. 
Has anyone else been through this or going through it?
I'm in my ovulation time right now and just trying to stay calm. AF is due July 18.
