Anyone?? Please!

So our 3 month old baby has been unwell for a week now, diarreah, projectile vomiting ans being unsettled.

About half hour ago, my boy coughed up blood in mucus. Was enough for concern.

Phoned doctors for the 3rd time today, as 111 said we would have an appointment for him to be seen about his bowel movements...

rung 111 again and ended up having to ring 999. To tell us that he needs to be seen but there's a 3 hour wait for help and possibly a 4 hour wait in a&e. So been told to make our own way up. Which I'm currently doing.

Anyone had this and there LO was okay? I'm in full blown panic mode and need some reassurance. I don't like seeing our boy so unsettled and unwell😭
