Pitty party...I'm entitled, right?

I've been on an emotional rollercoster the last few weeks. I had a period 8/24-8/31 then started bleeding again 9/7 & I'm still bleeding. My moods & emotions have been all over the place the last few weeks. I've been angry, depressed, confused, jealous, etc. They change so suddenly & for no reason. I've felt like crying mostly today & I almost can't help myself. We've been ttc for a little over 2yrs & because of wonky periods have gotten no where. I'm disappointed my husband's disappointed & I'm beginning to feel like a big failure, like I'm just not capable of becoming pregnant....I'm just having myself a big pitty party...
