Hay nako, sis, sounds like pregnancy discomfort na talaga pero kailangan mo talaga na i-check with your OB ngayon na 34 weeks ka na, yung pain sa singit, loss of appetite, at dizziness pag biglang tumiayo could be a mix of things na kailangan tingnan ng doctor para sure, especially the dizziness part kasi that's not something to ignore sa ganitong stage. One of my mum friends had similar pain down there at sabi ni doctor niya combination lang ng pressure from baby and ligament stretching, pero may iba pang reasons din kaya better safe than sorry talaga!
