The fact that you're TTC in itself shouldn't change your cycle, but it is possible to have the occasional shorter/longer cycle. Do you know if it was shorter because you ovulated earlier or your LP was shorter? It might be that your cycles were longer coming off BC and they're adjusting a bit.

Mine can vary by a few days, but it's been doing that in the 6 months since I've been on BCP. But a variance of 4 days is pretty normal for me. I temp so I can usually tell when it will start based on O, even though the cycle day of O changes, if that makes sense.
I like temping for that reason-- it's nice peace of mind knowing exactly what's happening when. AF a few days early is not a fun surprise.

@kpow: I regularly O between cycle days 18 and 20 (I temp to confirm), so my cycle could be 2 days shorter or longer depending on that. I've heard that any little thing from stress to sleeping poorly, to alcohol, exercise, etc can affect when you O.

If your luteal phase (between O and AF) is getting shorter though that could be an issue, but only if it's less than 10 days. I only mention this because you said you were spotting before AF.

PS - feel free to join us in the charters of the hive thread if you do start temping again and we'd be happy to analyze the crap out of your chart/symptoms

My cycle is regular. It's typically 30-32 days. Since I started tracking them to TTC I have had one 28 day cycle. I
