Aaah mama, alam ko yan, that weird feeling na parang may wrong pero walang specific complaint, super frustrating talaga! Honestly maraming mums sa group namin nag-share ng ganyang experience mid-pregnancy, parang combination ng hormones, exhaustion, at the physical toll ng carrying baby na hindi mo ma-articulate. Since everything checked out fine sa OB mo last week and your vitals are all normal, it might be pregnancy fatigue or hormonal shifts, pero since you're feeling this way pa rin, I'd really suggest message your OB about it or go in for a check-up kung hindi ka pa okay by now, better safe than sorry, di ba? Rest as much as you can, and if the feeling gets worse or mas may specific symptoms na lumabas, don't wait for your scheduled visit na.
