I think I understand why we talk about 1st trimester pregnancy depression.

I am only hearing speaking about risks and physical malformations, from others, partner, book and internet. 

Me it's even worst.

I drank and I smoked until week 6, I was in holidays, I had no clue I was pregnant. I swear I would have never let me hurt my baby.. I just didn't know.

I was so happy, now I'm just terrified and feeling deeply guilty.  

Why people just talk to you about 

miscarriages / malformations / risks risks risks risks risks ... ? 

Now, guess what, I am under pressure and I am depressed. I can't do nothing to change what happened.
