I have a seroma post op 4 weeks abdominoplasty it is leaking continuously from incision line, is this normal? (Photos)

Seroma bursts approx every 4 days has happened 3 X now. Will burst from incision line but continuously leaks yellow fluid. Last eruption was 3 days ago it was approximately 3 handfuls of blood fluid not the yellow serous fluid? Doc is aware but see him in 3 months. I feel pressure and a build up prior it bursting. Which i have now so i am waiting for it to happen again. The scar line is a concern as it is always moist from the fluid even though i change the dressing regular. Any advice? Thanks
