Hi rainbowmoon, I don't have an answer for you, but I am in the same boat from what it sounds like. I have spotting for a few days, then it goes away for a day or two, and then my period starts. How long are your cycles? Are you taking your basal temperature to know when you ovulate? I called my midwife to ask her if the spotting could prevent me from getting pregnant, and she said it's not likely. I've been trying to do as much research on this as I can, but I haven't been able to come up with much. We just barely started TTC, and I already have 2 sons, so I really have no reason to think that it will cause me any kind of problems getting PG. I'd be really interested in hearing what the other responses are to your question, though. Good luck!
