Crying 😢😭

Is there a reason why we cry so easily during pregnancy? My SO can be an ass sometimes & sometimes i'll get really upset about it and cry. What gets me upset is when he yells at me and calls me a retard 😔 over dumb stuff. Then he gets mad at me if i cry because he say it's "for no reason".

Like how about you try being pregnant and having all these changes in your body 🙄. I wish he could understand...
