Im 29+4 i know how you feel my insomnia started last week too. Its called third tri insomnia it's normal unfortunately.
I totally feel u I'm the same way I'm 27 wks and I sleep in a bed with my 6 & 7 yr old and it ***** really gotta accommodate and fix the room to add another bed :/.... but body pillows help....maybe a shower with lavender body soap I typically use Johnsons brand for adults it relaxes me and soothes :) good luck
