Tightenings only lower of belly only, often....

Lol I am laying down (nana in bed early) perhaps I should get up. They aren't painful just noticeable and slightly distracting.

try to distract yourself with something else and if they keep annoying you then perhaps start timing them. If they appear to be regular then it would be worth getting checked out as your baby is still premature and they may want to help stop you labouring.
