Pregnancy sickness third trimester

Megan

I’m 30 weeks today and the last month been in and out of Drs office and a few hospital visits. Started with spotting then cramps/contractions but also a pain in my abdomen,nausea and loss of appetite as it got worse my dr decided to do an mri to rule out appendicitis...luckily it came back negative said it could be a bug just keep my eye on it,call if I got worse and he was going out of town this week. Then my youngest caught the actual stomach bug and then myself my oldest and husband..just got over that now I am having chills, aches vomiting and diarrhea and can hardly eat anything wondering if anyone else experienced something like this and what it was I’m trying not to worry but it’s hard and I can’t decide if I should go ahead and call the drs office for their opinion or wait a week until my next appointment my main dr will be back Monday. Opinions please 🙏
