Saggy boobs while breast feeding?

So I’m 3 months in, and I love it soooo much. It has been pretty easy going for me. But I’ve noticed that one of my boobs is a lot more saggy than the other one? Like it feels elastic and droopy. I can pinch and pull my skin and it’s super long compared to the other one that feels way more firm.. is this normal?

Compared to barely being able to pinch my other boob..
