Do the hormonal changes when you're pregnant?

My moods would go all over the place. I would be angry and grumpy and the next minute would be crying about absolutely nothing at all. The hormones during pregnancy are very similar to the hormones premenstrual so that is why some women will find that get moodier. I know most of what I did when I was pregnant were more or less get upset easier. I would be so happy and then a sad commercial would come on TV and I would start crying. I think every women will experience it differently. I know more of the anger and depression can come after birth with the hormonal withdrawals as your body starts trying to balance everything again.
