Spotting on CD12?!

Nicole
Hey Ladies,
This is probably TMI but hey, we're all in the same TTC boat. So today is CD13 for me. I took 50mg of Clomid from CD3-7. Yesterday on CD12 I had horrible cramps and a persistent headache that ran all down the left side of my face into my neck. When I got home I noticed some bleeding with a little bit of clotting. The bleeding has since stopped but I'm concerned. 😔 Has anyone experienced this? Does this mean this month is a bust? HELP!
