Congrats on your twin pregnancy, mama! It's totally okay to switch sides, left side is generally recommended kasi mas maganda ang blood flow, pero kung nasasakit ka or nahihirapan ka huminga, listen to your body na lang at mag-right side ka when you need to, the important thing is comfortable ka at makakatulog ka well. Siguro best to mention this sa OB mo next visit para sure na lahat okay with your twins, pero honestly maraming moms nag-shift ng positions throughout pregnancy kaya you're doing fine! You've got this, at ang self-awareness mo na ito shows you're taking great care of yourself and your babies na.
