Weaning and TTC

Rachel

We are on our first month TTC baby #2. It's also my first full cycle since my 2 year old finished weaning. I had been ovulating on day 17 of my cycle (I track whether we're trying or not because of migraines) but today on day 13 of my cycle I got a positive OPK. Has weaning changed anyone else's cycle this fast? I also had a light, short and easy period this month, which is not my usual at all!
