Im going to pull my hair out!

I don't wanna sound like a bad mom because I'm not I really love my son to death! But past two days he's done nothing but cry I've given Tylenol for teething that didn't help ive tried sweet oil for ear ache that didn't work I've cuddled him love on him all he does is push me away an scream an cry! I wanna slam my head into a wall at this point! He's never cried so much before. He's throwing things an hitting. He's got to the point he will throw a fit in the floor to clawing his face to doing a backbend an screaming bloody murder over me just telling him no. I have no idea what's got into him but I'm going to throw a mommy fit in the floor soon. Maybe because I'm pregnant? But I don't understand he's been just fine this whole pregnancy. He's only 8months old so whooping him isn't an answer.
