Just been to 2nd appointment and wish I had lied!

Feel awful! I have just got back from the consultants after being on metformin for 3 months with having 1 period! I got told at my 1st appointment that if I wasn't pregnant in 3 months I'd be given clomid to help us conceive! When I went today and saw the head honcho he asked if I'd had a period to which I answered honestly so he said therefore carry on with the metformin for another 3 months! He said that I MAY ovulate even though I have been using My CBFM and know I haven't this month! I left in tears! I really thought I'd be pregnant by the end of this year but now I know I won't be! I don't feel any better on the met and think my period was just coincidence! The more I think about the more down hearted I get! I so want to be a mummy, will I ever get there?
Sorry for the rant I just needed to let off steam!
I've got a wedding to go to this weekend where people are going to be asking me about having babies! I don't know how I am going to cope, feel like I'm spiralling into depression!
So sorry to off load on you x
