I had a miscarriage 4 years ago and never conceived since. I never drank water but started drinking lots of it the last 6 weeks and I'm currently 4 days late for my period and have had tender breasts for 2 weeks and nausea the last 4 afternoons. I don't want to test yet incase I've got my hopes up for nothing. This is the only thing I've changed in my lifestyle, could it of helped??
