Lovely haha just adds to the frustruations

So put new oil and coolant in today, after flushing the system yesterday and as soon as I started the engine up the coolant foamed up again, but seemed to die down after a little bit. Could it just be the water pump sucking up any trapped air in the system and foaming that way?? I'll keep an eye on it over the next fee days and see if it goes away
