Would you quit this job?

I get paid $8.50 an hour. I work 9 hours a week in person, sometimes less and sometimes more but never more than 15 hours. I get paid between $250-$350 a month because I only get paid for in person hours. I’m the supervisor so I make the schedule, deal with call outs, do write ups, etc. all while I’m at home. I took my kids to GA for their birthday yesterday and ended up getting 30+ texts about schedules and call outs for that day. All of which I ended up having to handle. This is every freaking day. Boss won’t give me a raise and I can only add 2 hours to my time to account for schedule making, nothing else. I’m so over it. I just want to quit! I’m 13 weeks pregnant and a mother of 3 year old twins too.
