Strange

AF came yesterday for me. A couple weeks ago, I had experienced some spotting and just believed it was a light AF. I feel like my whole cycle is off now. I've been very stressed lately,  had a death in the family and my wedding is next month. So I think that's what has been going on. It would mean that my real AF was a week late and that I had spotting for a week. It's just strange to me. This would happen to me the first month TTC. Does anyone else have an irregular AF? Does it hinder you in TTC at all?
