I woke up this morning feeling fine, went to loo and had the most horrendous cramps. I got my period which explains the cramps but I soon passed out after and got sick. DH held me so I didn’t injure myself. Lying in bed but still feel quite weak and nauseous. No temperature, had 2nd AZ vaccine last week. I’ve never had painful periods to this extent so am alarmed what this could be, will ring the GP for advice but has anyone had this ever?
