5 month old spitting up a lot?

My daughter is 5 months old and she had reflux up until she was 4 months, the doctor has cleared her from it, she has been off of her meds and is doing great! Unfortunately, she has begun to spit up a lot after her feedings and I don't know if I should worry about it or not. She drinks a 6oz bottle and of that, I would say she spits up at least 1-2oz if not more. Should I call the doctor, or is this normal?
