Ok so does this happen to anyone else? Every single time after my period ends There will be days where my head hurts like crazy and I feel really nauseous to the point where I actually throw up I'll also feel lower abdominal pain either on the left or right side but it's mostly left side and I'll have a small fever with it. Does anyone else go through this? Cause my doctor told me it was totally normal cause my hormones changed after giving birth.
