Low Placenta -- what exercise can we do

Hello mummies with low placenta during pregnancy! May I know what are the exercises you have done and are comfortable with doing? Do you still do pelvic floor exercises? Yoga? Nature walks nature reservoirs and nature parks? My gynae says no strenuous exercise. I read about no squats. I have no gym or yoga membership. Not sure what exercises are safe for me. I'm only going for walks around the neighbourhood. #advicepls
