Clueless

Okay so fellow ladies need some knowledge please. The past three days (since my period ended) my appetite has gone down and my sex drive has gone up. Usually I am a monster eater. I'm 107lbs but eat like a 300lb man normally. Reasons? Also My inplanon expired over a year ago and my period just started to regulate. And this is my third regular cycle that just ended. Glow says I'm ovulating starting today and as usually the BF and I have been going at it so fingers crossed! :/
