Bleeding (tmi)

Hey ladies I have a question. It may be tmi but I have to ask. I found out I was pregnant last Wednesday. Yesterday day my guy and I had sex and during intercorse he noticed a puddle of blood so we stopped. Today there was no bleeding at all. My first docs appt is tomorrow. Has this happened to anyone of u? This will be my second kid and it never happened with my first born. Heeelllppp 😩😩
