hi everyone, hopefully this doesn't seem like a dumb question, given the health anxiety that we deal with. for the past two months, the day before or the day that my period starts, i have gotten a bad headache and, more concerning to me, severe nausea, where i cannot eat anything, am puking out bile (that yellow stuff) and hear liquid sloshing around in my stomach. has anyone else experienced any or all of these symptoms? just curious. i might see my doctor about it because i read that this could be due to a thyroid problem and i was on medication for hypothyroidism but discontinued it almost a year ago. thanks for your time.
