paranoia during pregnancy

🤰💙
So I'm 18 weeks pregnant and I've always been a brave girl, today for
Some reason I planned on taking a shower before hubby gets home
He's a cop so his schedule is 3-11 anyway I never care to shower a lone or falling asleep by myself but for some reason today I go in the shower and i  felt scared so I want to know if this has anything to do with pregnancy maybe or it's just me and it's all in my head lol
