<<<I too wish to know what causes menses to resume rapidly. My period returned at 10 weeks PP. I carried my son everywhere in my arms when I was not sitting holding him in my arms.

I have 5 children and only with one did my menses return early - 11 wks. I have leaned toward weight gain as the reason, also. This was the only pregnancy during which I gained a large amount of weight - 50 lbs - and kept it on for some time. I also experienced severe hot flashes at night postpartum and vicious nausea with MER. I have been looking for an answer to this scenerio as I can see many woman weaning if they had to deal with these symptoms. I have read that excess weight will influence estrogen levels (as in; it is a good idea not to be underweight entering menopause, symptons will be milder with some extra weight on your bones), also realize that oxytocin of MER can produce nausea. Any professionals able to comment? Has anyone else experienced this or had a client with these problems? Judy Hain - in Cape May County NJ
