I've been taking the birth control pill for about four months now. I've taken every single pill each day but between 8/10 in the morning. I use condoms aswell. 

i was on the pill two years ago but stopped taking them. I started these ones again, same brand, but for four months of taking them when I have my period, it's short , I only bleed after taking the pill and stop a few hours later until the next day.

I've been quite stressed lately and I feel sick until I take my pill in the morning sometimes. i have these moods where I don't know what's wrong. 

Is this just me being silly and stressing? Or is it a side effect of the pill? 

Im in no way able to take care of a child as of yet, I'm not emotionally stable to go through pregnancy, reasons why I use multiple forms of contraception.
