I'm EBF so not expecting any periods soon. There's no smell or discharge. And I feel ok. But on days when I've been very active, lots of walking for example, I get niggly achey back and lower abdominal pain. Nothing major but annoying. It's 3 weeks before my check up, and I'll ask if it's still an issue then - but in the meantime, anyone else had this trouble and will it resolve?
