My body is playing tricks on me :(

Catherine
My husband and I have been ttc for over a year now and I found out I have pcos so I'm on my third month of metformin. Two weeks ago I was able to track me ovulating with opk's and a few days after my breast started feeling a little tender and they got more and more sensitive each day. It got to the point where I could barley stand giving my husband a hug because it hurt so bad. I never get sore breasts before my period so I thought this is it! This is our month! Then yesterday the pre-period cramps started so I waited another day to test and this morning bfn. I still haven't started my period but it's suppose to start today. I keep praying that somehow that test wrong but I know it's not. I just don't know how much longer I can handle this heartache. And it seems like everyone around me is pregnant. I'm trying to trust that God has a plan for us but it's difficult some days.
