Nausea Help!

M • UK. TTC Baby#1 . Partner Low Sperm Count. Polycystic Ovaries.

For the past 5 days Ive had severe nausea and vomited nearly everyday. Already 2x this morning and I'm fed up. I finished my period yesterday I'm not pregnant😐

I have a doctors appointment Wednesday for another issue and will be mentioning this but i dunno why this is happening.

(I have also had diarrhoea) but i feel dizzy, sick and tired where i keep waiting up thinking I'm gonna be sick🤢🤢

Anyone have any idea what this is? Period? Bug?😭😭
