Pregnancy mood swings & PPD/PPA

With my first pregnancy I had no mood swings during pregnancy and no baby blues/PPD (I did have some PPA though). Now I’m pregnant with my second baby and my first trimester this time was full of mood swings. I’m just wondering if there is a link between how your hormones handle the pregnancy and how your hormones handle post partum.

Have any moms noticed a pattern with their personal pregnancy symptoms matching post partum symptoms? I’m really scared of PPD and felt so lucky and glad to not experience it the first time, despite a lifetime history of depression.
