Did I do something wrong?

This is gonna be something silly but I need your guys opinion. Last night I felt like I was leaking (thought my period arrived) so I grabbed a wipe and kind of hid it on my pj shorts (big mistake, I know silly) as my partner was coming inside the room I was waiting by the door to go to the restroom. He wanted me to give him a hug and I didn’t lift my left arm because I was holding the wipe with it and I started laughing (nervous laugh) because he was like what are you hiding? and as he kept looking he just kept getting angry and I was giggling because it was a wipe and that looked silly. He got so mad he started telling me that I’m cheating on him and he doesn’t want to be with me anymore. We actually have a 3 year old son together. He started telling me how I never wanted a child with him and he told me to leave and that I was a cheating bitch. He went as far as lying and saying that he also felt that I was hiding a box. I said what? Where am I hiding a box? I was only hiding a wipe because I thought I had gotten my period suddenly and I freaked out a little and wanted to rush to the restroom. Yes it was my mistake for hiding it and making it look suspicious but that’s all. Now it’s 6am and I’m laying here with our son and he left to work without saying one word. What should I do ? He has accused me of cheating in the past for absolutely no reason. He checks my phone and I have nothing to hide.
