At this stage, you must start pampering yourself with comfy nightwear, prenatal massages, photoshoots et al. Basically anything that makes you feel good. This is also the phase when your grandmother might tell you to not stretch your arms over your head, as this could get the baby entangled in the umbilical cord. This is a complete myth. On the other hand, doing some overhead arm stretches every day might help you relieve the discomfort in the ribs especially in the last few weeks of pregnancy.
