Emotional & Exhausted

I've been feeling really emotional the past two days. I want to cry at everything. I've been crying when my husband has said a comment. Nothing bad if you were on the outside of the conservation. I've also been really tired. Today at work I could have taken a nap. My coworker even made a comment about me yawning way to much. Just curious to if my cycles are finally back to normal after being on BC for so long.
