Am I wrong for pulling a cheating prank on my boyfriend?

Okay so me (19) and my boyfriend (22) been dating for almost two years and we have our first baby on the way and lastnight I decided I wanted to pull a prank on him by sending him a picture of me cuddling up with another guy (although it wasn't me I made my Bestfriend send a picture of her and her brother legs which made it seem like I was really cheating on him because they were in a cuddling position... I know it's kinda weird lol) but I sent the picture to him and he immediately showed up to my house and he was very emotional and upset about it he really thought I cheated on him and I kept acting nonchalant because it wasn't even true and he thought I just didn't care about him or the relationship anymore because he thinks I found someone better but after he left I sent him screenshots to show him that the female in the pic wasn't me and I never cheated on him and I told him it was a joke but now he's completely ignoring me with no explanation he won't answer my calls or texts at all am I wrong for pulling this prank or is he just overreacting? And what should I do to get him to talk to me if I am wrong?
