Thought I was over it...

....was initially super emotional during MC for week or so but then felt like I came to terms with. Started to TTC immediately but this last week (af or BFP due) I've felt incredibly emotional again and lots of sadness.

Is this typical?

Do your hormones go insane after pregnancy or should it be back to how it was before I had ever been pregnant?

Or is it due to rising hcg levels and I could be pregnant? .... (hopeful)
