Ay, mama, I feel you, ganyan din ako around that time, super uncomfortable talaga! Pero honestly, the rashes and pain after urinating ay worth checking with your OB kasi it could be a UTI or yeast infection, common sa pregnancy pero kailangan i-treat properly para hindi maging problema. The pelvic pain (singit) is usually normal ligament stretching at yan na ang sign na malapit na, pero combined with rashes at urinary pain, better safe than sorry talaga, message your doctor or go to the clinic para ma-rule out infection, especially this close to delivery na.
