So I started taking this 6 days ago it's a 7 day thing. Anyways I had yellow green discharge so my doctor prescribed me this I'm 13 weeks pregnant. A week before she prescribed it she tested my urine for any infection and there wasn't any. She still prescribed it. I'm still having that yellow green discharge on the 6th day. Should I call my doctor again or what until tomorrow? And I'm still thinking this is my mucus plus but this is my first pregnancy so I don't know. I'll put the discharge in the comments!
