can implantation bleeding come out with semen?

long story short-

my so and i were bd and i felt something deep within me hurt for a slight second, like a pinch. he came in me and then i hung out and went to the toilet and this pink semen came out of me with a little red dot in the middle... idk if it’s implantation bleeding i scooped it up w my pee container for tests and here it is in all its glory
