I can ovulate without much EWCM, some cycles I notice it and others I don't so it is possible. If you're concerned about your cycle maybe see your gp, they may be able to order some blood tests to see where you are in your cycle. It may be that your cycles are a bit out after being pg, but if it's different from what is normal for your body I would go to the dr's for peace of mind. Good luck, hope your TTC is short and sweet!
