The general precautions to be taken during the first trimester are - avoiding intercourse, taking as much rest as possible, avoiding lifting heavy objects and rough journeys and stress
. Placenta can be said to be low-lying only after late second trimester; now, as such, it is of no significance. The placenta usually goes in to the upper part of the uterus
as the uterus enlarges. Please continue with the medication and relax.Wish you good health.
