Sunday I came on my period.. I was fine during the first hour then began having pains I ended up turning a yellowy grey colour before passing out for about 2 munuits , I went to A&E n seen an out of hours GP n he prescribed me some paracetamol n cocoadamol n told me it was normal for the pain to make me pass out . Does anyone else experience this, n was there a reason why you were experiencing this amount of pain due to menses?
