Should I go to hospital or am I over thinking?

2 days ago I had a small (pink) amount of spotting, lasted only the 1 toilet trip. Today I have had more spotting (pink) but it’s a lot more than before. And even had a red bit. I’m 16 weeks and 1 day. Should also mention I’ve been sick the last 2 days with gastro incase that would have anything to do with it. I’ll put photos in the comments.
