Still spotting

I thought that I was going to be lucky and only have a 6 day FP (including spotting). I stopped spotting on Wednesday, but it started back yesterday and I'm still spotting today. I took my last clomid today and I'll be starting on my estrogen tomorrow. D is off tomorrow, but he leaves for Alabama some time on Sunday and he won't be back until Friday. I'm trying to think positive thoughts about when I'll o (like that D will be in town but it won't be as late as usual), and that our timing will be good.
