Ganyan talaga ang umpisa, lalo na pag repeated pregnancy, ang bloating at back pain ay super normal sa week 6, kaya yan ang main culprit ng sleep disruption mo. I get it na nauuwe ka sa sariling luto, pero try smaller frequent meals instead of big ones, at don't force yourself sa fish kung ayaw mo, stick sa cravings mo like lechon para least kumakain ka, at maybe ask hubby or someone to cook para iwas sa nausea trigger.
Pero if the abdominal pain gets sharp or you spot any bleeding, check with your OB agad-agad ha, because some pain is normal pero some needs checking.
