Hello everyone! Who slept during pregnancy? I heard that it's best to sleep on the left side... but I can't, I often wake up on the right side, sometimes I lie slightly on my stomach with my leg raised, and on my back. For a couple of days now, I noticed that regardless of position, as soon as I start feeling like my lower abdomen is being pulled, it goes away very quickly, sometimes I wake up from this, but it also goes away quickly! Who slept like this and how did you feel at week 16!?
