TMI- Anyone experience this?

I had this once last week and then again today after being intimate with my husband. Was light pink when I used the bathroom after ejaculation and this was a few hours after. Same as last time then went bad to creamy cm. We have been together for 5 years and never experienced this. I also have pcos and do not ovulate on my own. Not sure if maybe this is ovulation or implantation related or not. Any advice is appreciated!
