Why does the universe fuck with me?

Three months ago we decided to end our fight with infertility.  We were blessed with a happy, healthy little girl, and emotionally, I just could not handle everything that comes with trying (and failing) with "broken lady parts."  It was a tough decision, and one that was not made lightly.  Eventually, after a bit of a rough patch, I made peace with that decision.  I started working on myself.  I had 2 years of baby weight & infertility drug weight to lose.  After 3 months of eating healthy and exercising, it looks as though my period is returning.  WTF???  I know PCOS can be helped with weight loss, but I haven't ovulated on my own since my early 20's...long before I packed on an extra 15-20 lbs.   I don't know if I am actually ovulating, but will go back to temping this month to see.  If I am, it looks like we have another decision to make.

Like I said, I had made peace with not having another child.  Part of me was even relieved that I wouldn't have to go through the sleepless, anxiety ridden, tear filled nights again.  So what do we do now?  We haven't been using birth control and had said if it happens it happens, but I think I was only ok with that because I just didn't think it would happen.  I am being selfish and a little vain.  I am finally getting my body back.  Maddie can entertain herself some, and doesn't require constant attention.  I don't really want to have a kid at 35 or older.  I know these are stupid reasons, and maybe they are just things I invented to convince myself I was fine.

 I just hate that at the moment I was ok with the way things were, the universe decides to fuck with me some more.
