Implantation spot?

Hi !

I wish I took a pic but it slipped my mind . I am 4 days post ovulation . Had sex 2 days before ovulation and 2 days a go . I had slight cramping yesterday... and I know TMI but also had 2 orgasms last night and when I went to the bathroom and wiped I saw faint pink CM and looked closer and saw what resembled uterine tissue but a very small amount . Was wondering if this could be what they call implantation bleeding or spotting ? This is my first experience trying to conceive and it’s been since August and all negative results .

Thank you for your advice !
