I'm being treated from a suspected short luteal phase. I know for a fact that I ovulated 12 days ago (as I've been having ultrasounds to pin point it). I've also been having hcg injections to support my luteal phase. Yesterday I had brown spotting and since then nothing apart from cramping. So i'm now not sure whether the spotting would interfere with getting pg. My cycle has been like this since having ds 2 yrs ago. Just wondered if anyone else has regularly had spotting for 2/3 days before af arrives and whether it will stop me getting pg?
