I am on my second cycle of clomid. Just had a very light (2 days brown spotting and 1 day red flow) AF. Last month was pretty much the same. I am now worrying that my uterine lining is being effected by the clomid. Any ideas? I can call doc tomorrow, but wanted thoughts/ advice/ experience. I'm gutted as its been such a long and heartbreaking journey to get this far and I hoped the clomid would sort me out.
