I think like the website says, every situation is different and some women might be fine with just taking a natural herbal supplement, however if the depression is more serious a more aggresive form of treatment might be better.
I can understand that you would like to connect with someone who were in your situation because taking anti-depressants needs a serious commitment because you can't just take it for a few days and then decide on something else, one needs to take it for a while to start experiencing benefits. And obviously sometimes medication has very unpleasant side-effects which won't be ideal at this moment.
I am not pregnant at the moment (but planning baby no.2), however strangely I felt the least depressed while pregnant with my first child (except for the first trimester!

). I struggled with mild PND and a few months of Eglynol was enough for me.
Whatever you decide, please look after yourself! xx
