hi there, just to share my experience, i am currently with only 2 dos vaccinated, and positive covid on 37+4. To be honest I was really in panic mode as I am already so near my due, but lucky my symptoms are mild, only coughing and blocked nose. As usual, I practice quarantine and manage to be negative after the 8th day. When delivered my baby (on 39+6) I was also worried that covid might infect my child, but child specialist ensure that Covid usually won't pass down to babies in the womb... they also did rtk test on my newborn and result is negative... if you are worried, try talking to kk nurse or your obstetrician for further information... hope it helps...
