Hi, I finished my period last Monday, it went for a week. But now I m feeling sluggish, I have incredibly bad bloating and cramps , Pains up and down my legs, back pain , I m very tired and can t eat. Iv also been having brown/red like period flows... I usually get this after a period but only for 2-3 days And never get these sorts of pains.. Could I of had a miscarriage and not known??
