I heard a popping noise in my stomach after a fight. It lasted for 10 minutes. Was this the baby?

I’m almost 18 weeks and have not been having a good new marriage. We have no days off work together and do not talk at all after work. He’s silent even if I talk to him. We have a bad financial situation that he doesn’t acknowledge and we do not go out, celebrate any holidays with gifts or cards, we can’t afford clothing or anything after we pay the mortgage or utilities. Food is also a problem. We are literally like roommates in college who don’t like each other.

Last night we got into a screaming/yelling match right after he got home from work. I heard a popping noise in my stomach after that went on for 10 minutes. Was this the baby? I think the baby was upset.

Did anyone else ever have the pop corn feeling or noise?
