Low red blood count

Hello moms! I recently got my blood test result back and turns out I have a low red blood cell count. I’m supposed to see my gynae in a week’s time for review of those results and NIPT result. But would like to know if there are any tips to increase red blood cell count by changing diet, instead of just depending on iron supplement? I also have a fear/phobia of swallowing pills/tablets/capsules, so any clue if gynae can prescribe some sort of iron supplement in the form of liquid? Thank you in advanced!
