1st time mum: Breastfeeding

I noticed my nipple does not output a lot of milk though I can feel there's full of milk in my breast it jus not coming out, when I hand press it I only see 1 or 2 outlet from my nipple that dispense the milk, I asked my confinement nanny, she mentioned my nipple outlets are block or not open to dispense all milk in my breast. ( it's not nipple blisters). Should I get lactation consultant or is there any one that could provide me some advice
