So I'm asking for my sister as she doesn't have this app, she's about 4 - 4 1/2 weeks she's suffering from severe back pain and even tho her doctor and the lady on 111 said she's fine, she's experiencing very dark brown blood (which they told us is old blood which is fine) coming from her which started pretty small amount on about Wednesday only on the tissue after she'd had a pee but it's increased to more now, kinda like a light period (but not red blood but still dark brown) with small dark brown clots this would of been round the time she would of had her actually period. She's having some cramping when she's been on her feet for a while, I haven't got children myself so don't really know how to comfort her but if anyone has experienced this please let me know so I can try and put her mind at ease xx thank you
