Light brown discharge

No po, wear a pantyliner and take pictures para mapakita sa OB. I started having a light color discharge on my 23rd week like once or twice a week then nagpprogress yung color every week to light brown, reddish brown, light pink to red. I’m now on my 29th week and was advised to complete bedrest until I give birth with medications. Have it checked po para malaman ano cause ng discharge mo. Stay safe.
