Pink watery discharge

Elizabeth

Had a miscarriage back in October and bled for about 10 days. My cycles went right back to 28 day cycles. Period started January 10th this month and according to Glow the 20th was my first fertile day. Had sex that night. The night after while in bed I felt discharge passing. It was like a mini waterfall of pink watery discharge. It went through my underwear and PJ pant. Wiped and that was it. Couple days later I thought I saw light brown creamy discharge once. Might have been my imagination. Has anyone had this?
