Unvaccinated, 4 Weeks Pregnant and On Quarantine Order

Hi! First time getting pregnant. My MIL who lives with us got tested positive for Covid. Thus, Hubby and I are on QO. I am 4 Weeks pregnant (via SOIUI) and unvaccinated. Due to the QO, I have to postpone my 1st scan from week 5 to week 9. I am worried about my baby. So far, hubby and I have tested negative. I am not sure what to look out for these few weeks and I am unable to visit a doctor during this time! Would appreciate some advice. #pregnancy #1stimemom #firstbaby #pleasehelp #advicepls
