I was wondering if anyone has heard of a correlation between weight and how soon menses return? Mine was back within 4 months despite constant nursing. I'm plus-sized, and my mom said that she heard that the lower your body fate percentage, the better ovulation is suppressed. Not to confuse the issue, but I didn't appear to be ovulating for about thirteen months, so the bleeding was probably breakthrough bleeding, but it was confusing because it was regular, like a period.
To Michele- I've heard of a lot of women getting PMS symptoms, or even having a change in the breastmilk around time of usual menstruation. I'm not totally sure, but someone told me it was a sign that ovulation will return soon.
