Hello!
I wanted to ask if it's normal for periods to just kind of, be a bit weird sometimes? I usually have cycle of between 4-6 weeks, and I pretty much always get painful cramps throughout and painful breasts. Lately though I'm noticing little to no breast pain and not nearly as much cramping, as well as some very brown menstrual blood last time. Can uteruses just do this sometimes? Can they often change over time?

Yep, it's very common for periods to change over time, for cycles to fluctuate, or to have different symptoms from one cycle to the next. None of that is unusual! We have some more in-depth info on menstruation here, which you may find helpful: On the Rag: A Guide to Menstruation.
