I too would suggest you go see your GP. Take your partner with you so that he may start to understand why you are feeling/behaving the way you are. If it is depression, your GP will be able to tell you and offer you some advice.

Your hormones are all over the place right now, they should ease off shortly, at around 12 weeks your body finishes creating the placenta and I found that was when my moods calmed down a lot.

Maybe also Google hormones or moods in pregnancy and see if you can find some info to show your partner.

Wishing you all the best .
