I am just shy of my 35th b-day and I have been trying to conceive for 14 months. I completed my second cycle of clomid in April. I had a positive opk on April 20th. I was supposed to get my period May 7th. AF has still not come. I just had an ultrsound and I seem to be mid-cycle. Has anyone else had this problem? I am getting extremly frustrated and I just wish I understood why I don't seem to be working properly.
