I'm noticing that my chest seems okay overall, but my nipples are unusually puffy. When I touch them, they squeeze, but there's no pain involved. Should I be concerned about this, or is it something normal that happens sometimes?

It sounds like you might be experiencing normal changes in the breast tissue, which can happen due to hormonal fluctuations, especially during pregnancy or changes in weight. As long as there's no pain or unusual lumps, it's usually nothing to worry about. However, if you're concerned or notice any changes, it's always a good idea to check with a doctor.
