Second round of clomid failed. My luetal phase this month was too short! I ovulated on day 14 and AF started 9DPO ive had the most awful cramps and it's been like a fairly normal period but only lasted 1 day. Spoke to my fertility nurse and she's called me back in earlier than my next appointment which was the end of October now moved to September. I feel so disappointed I worry that although the clomid is doing it's job my short luetal phase is preventing any implantation from occurring. Now I dont know whether I should even bother taking my next lots of clomid! Any thoughts? Anyone experienced anything similar?? Please give me some hope as after nearly two years I'm starting to give up!
