Mama, please check with your OB as soon as you can, colored discharge like that really needs a proper check-up, especially if it started after taking new meds. Hindi kami pwedeng mag-guess kung ano yan, kaya importante talaga makita ng doctor mo to make sure lahat okay sa baby at sa'yo. A few of us moms learned the hard way na better safe than sorry when it comes sa ganitong changes. Anyway, your OB will know best kung related ba sa meds o kung may kailangan i-adjust. Fingers crossed it's nothing serious, but please don't wait!
