Baby stomach bug help!

Has anyone else’s baby had a stomach bug?! My son is 2 days away from 10 months and he was up vomiting all night. Like 15 times from 12-4 am. He was throwing up mucus when there was nothing left in his belly. Then we thought he was on the mend, only to throw up twice more in the late afternoon today. He seems happy, just extra tired... he’s still nursing often, but he doesn’t want to eat solid food. Unsure if I should take him to the doctors if it continues or if anyone has any advice from a similar experience. It’s so sad!
