Hmmmm…that is interesting.
I don’t remember after weaning my first son, but I just finished the weaning process with Nathan a couple of weeks ago, and I did notice frequent headaches. I just thought it might be due to seasonal allergies or something, but now that you mention it — it very well may have been due to hormonal changes….
How long since you officially weaned? Any other changes with you, maybe diet? Any unusual stress? Just throwing out ideas. Hope you feel better soon!
