What is going on?!

So the last two weeks, I've been dryer than a bitch down in my ho-ha and have no f-ing idea why. Today I'm four days according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, from my period and I have these cramps in my lower belly where my kitty starts. Like it feels like my period cramps but it's in the center. I am about to be 25 and realize my body could be changing hormonally but wtf?! This is not cool! Anyone else had this happen, I can barely sit down without it hurting. It's like a dull pain.
