when to worry?tmi lol

I'll just be walking around and all of a sudden get a strong urge to use the restroom and it's been diareah 😩 I'm 38 weeks. And I've been worried about if I'm sick does that mean my baby will be? If he has a bowl movement then he could get a lung infection and die. 

Is it pretty normal to have bowl movements like this when your like full term? Just a space issue? Lol pressing down on my bowls or something ? Obviously your not doctors but I know most of us go through similar things so just looking for some mommy advice💋
