My no DH and I had only been together 3-4 months when I feel pregnant with my DS.

Sometimes things are meant to be.

I am sure you will be fine - in my case I had untreated AND&A which manifested into severe PND&A as well, so if these feelings go on, please seek some outside support; counselling etc. Chances are it is just your hormones but an unexpected pregnancy was harder to cope with than I expected... just remember there is professional support, just in case!!!
