Advice pls

Hi y’all so obviously freaking out a little . Almost 8 weeks pregnant, had an early scan this week everything fine, strong heartbeat . Me and my OH have recently done the deed which does not happen very often and I’ve seen I have a tiny bit of blood in my pants. Can I have some advice please? There’s only a tiny amount and I’m thinking I wonder if I’ve cut myself down there rather than anything else. Thanks sorry for tmi
