THREATENED TO BE KICKED OUT WHILE 5 MONTHS PREGNANT?!

So my boyfriend and I got into a petty argument about shit. Literally. Dog shit! He was offended that I was picking the dog poop up ( pooper scooper) and taking it to an empty field instead of using the outside trash can. Referring to it as "trifling." He had an attitude about the whole thing. He asked something, can't remember what, and I answered and called him a smart ass. This escalated the fight. By the end of the argument he says " I will throw you out!" I'm 5 months pregnant! And i said " OKAY so you'd kick me out over a petty ass argument?!" To which he replies " YES because it's stupid and doesn't require any additional things to say!" So I'm suppose to take his attitude?! Fuck no. OUR ANNIVERSARY is in 3 days mind you. I wouldn't throw anyone out over a stupid argument. ESPECIALLY 5 MONTHS PREGNANT! I want to hear some opinions on this! Am I wrong here?!
