is this cm tinted pink? It looked like it but not sure.

 So I had sex on the 29th, he pulled out but I'm not sure if in time lol. I had two positive opks on 1st and 2nd. So I'm assuming I ovulated on the 3rd? On the 6th I also had sex and he finished in me. I've been tracking my cycle so we can figure out what time is the best time
To have sex and figure my cycle out. So I wouldn't be upset if I got pregnant. I'm just wondering if this looks a little pink and if it could be implantation? I did have mild cramping but for very little. I would be either 5-6 dpo today.
