I've got what feels like very mild period cramps, and have done on and off since my last period which ended about a week ago. Feel ok otherwise. I've had other months where I've had this mild feeling but have just brushed it off. Could it be an injection? I thought I may have thrush last week but that went away... I wee quite a lot but drink a lot of water and always have done. I'm off on holiday on Monday and no time for the doctor. I do however have a course of antibiotics I could take...
