Baby constipated 😢

My 2 week old baby has been constipated for 4 days already took her to the pediatrician today and said it was normal to give her a supository tomorrow if she still hasn’t pooped. I really don’t want to do that i’ve tried bicycle legs tummy rubs even gave her drops of water and nothing i hate seeing her in pain anyone know of anything else i can try to do before having to do the suppository thing 😓 i both breastfeed and give her formula as well.
