Anybody experience low lying placenta at 20 weeks scan? What are the dos and donts? Appreciate the advise.

I had low placenta and was spotting. With medi and jabs, spotting managed to stop. Gynae advised no exercise or carry heavy stuff. Walking in the house is more than enough. Have lots of rest. When close to due date, placenta managed to move slightly away. With the help of Gynae to monitor(including medi and jabs to stabilize bb and stop spotting) and advises, baby came out full term, 40w+1d healthy
