What do I do

I ovulated on the 15th of this month, I believe I had implantation on 9/10dpo. Today 14dpo I was suppose to start af but she never showed up . Checked cervix it was high and saw pink cm just like what I believe was implantation. Then it went away. Few hours later i am now having creamy white/yellow cm ... I took a test yesterday and this morning . Both negative ... and right now I’m just having creamy cm ... anyone have a feeling or suggestions on what’s going on ?
