Carbon monoxide

Left my car on to get rid of the ice and opened my front door for under a minute and it now has bought carbon monoxide in the house and the alarm is going off. Now I’m worried about my baby…I’m 22 weeks pregnant. My partner suggested to do it and I’m fuming. I literally run in to get some bags and my handbag and it bought all that in the house. Do I need to call triage? I’m so worried she is harmed and even worse
