Hi I finished breastfeeding my son the day after his 2nd birthday which is coming up to 3 weeks ago. I generally just feel dreadful! I'm up with migraines all night and day, had a constant one since Sunday now. I have had back back and belly past couple of days also, and feel sick on n off! Definitely not pregnant I've tested. Could this be anything weaning related!? Anyone have ideas what it could be or how long it'll last if so!? Thank you!
