Breastfeeding

My daughter is two months old today and all day she’s only been taking one breast for about 5 minutes then she’s done. I’m worried about her not getting enough? She doesn’t seem to be hungry until it’s time for her next feeding (2-3hr usually) is this normal? Her check up is tomorrow but I’m just wondering if any other mamas experienced this? I’m a first time mom and the only one in my family to breastfeed.
