Need Advice!

I have been doing fertility treatments since April and had my egg retrieval in May took a month off for embryo testing them started the Lupron and estradiol in July for a transfer in August.  Unfortunately I had to stop injections because my lining wasn't thick enough, that was July 29th.  I still haven't gotten my period yet, and my breasts are so sore and painful.  It has been a month now and nothing. Has anyone else experienced this?  Is it normal?
