Progesterone and discharge

For the ladies that took it vaginally have you had odd colored discharge? I thought it was blood but once I went to the ER they said no it's just discharge baby was healthy and to follow up with my ob, which I plan on doing...I'm just worried bc I'm off now that I'm 13 weeks but residual discharge is brown in color😕 and it's never been this way before...anyone else had this problem with suppositories?
