Baby hasn't had a bowel movement in 2 days?

me

Hi ladies, my girl is 4.5 months and exclusively breastfed. She eats every 1-1.5 hrs. She used to have a BM around 5 times a day, then slowly went down to 1 or 2, now she hasnt had one in 2 days but she is still peeing normally. Is this something I should be concerned about? I won't be able to see her doctor yet because it's a long weekend
