Hello, I am 26 yrs old and married. I have missed my periods this month and its been 12 days. Negative pregnancy test with watery and slightly white discharge and excruciating lower back pain ( i rarely get stomach ache during periods , only back pain). I had missed my periods 2months ago and did a scan and there wasnt such watery discharge or back pain. Scan report just said possible hormonal imbalance. I had pcod problem a year ago and is not there now.
