Pink orange discharge???

Hello ladies!

I know this is probably super tmi but I was hoping for some opinions/ideas as to what is causing this! My S/O and I had sex on the 1st and yesterday I started spotting a little, it was totally pink, and honestly not uncommon since it had been a couple weeks since we had sex. No pain or irritation or anything during or after. But now two days later the discharge has a slight orangish color to it. Has anyone had this before? And if so what caused it??
