Low-blows during the heat of an arguement?

How am I suppose to get over my argument with my husband..should I forgive him and just forget what he said? I recently had our son 3 months ago, and if you dont know, pregnancy takes a toll on your body..while we were arguing he blurted out "no hair having *****, you fat *****, and you ugly *****"..typing this is embarassing and hurtful.He got upset with me over something so elementary...He aggravates me daily, and I constantly ask him to leave me alone, and he refuses.He can be very immature and aggravating.I feel he is so oblivious to others boiling point, but wants others to stop when he askes...I don't think I can get over his words.Usely I bounce back during our arguments, but this time, I can not.
