Hey mama, okay lang yan na may something na parang lump or fullness sa left side, sometimes yan ay ligaments stretching, or maybe gas pocket na stuck, or sometimes kahit just how our organs are positioned lalo na pag pregnant, kaya asymmetrical ang feeling. Since sumakit sya Tuesday at nag-PT ka na negative, that's good, pero since nag-persist pa rin ang feeling na may something doon, I'd really suggest mention it to your OB just to be sure, para ma-check nila in person, better peace of mind lang, di ba? A few of us moms had similar worries and ang doctors namin usually said it was nothing serious, pero it's always best to confirm with your own doc para walang alalahanin ka. Hoping it's just one of those pregnancy things na normal lang!
