Irregular heartbeat

So yesterday was the day we were supposed to find out gender, we did.. But also found something not so great... Baby's heart beat sounded irregular and just weird.. The first time I went, it sounded really good. I just wanna know if this can really be normal? Everyone is telling me not worry, and it may not be a big thing but of course they're not gonna wanna stress me out and say it's this horrible thing. I just wanna know if that's true or not and if my baby boy is actually gonna be ok 😔
