My wife has been having almost all of pregnancy symptoms ( nausea , diarrhoea, sore breasts, etc.) since over a month now. We have done 3 urine hCG tests and recently a hCG blood test. All have returned negative. The Gynecologist whom we consult has advised to meet a Gastroentrologist. However, since yesterday she has started having white discharge as well. Could she be pregnant?
