Ay nako, I feel you, that cough is really tough especially pag malapit na ang important appointments mo! Have you tried asking your OB or the clinic about it bago mag-ultrasound? Better safe na lang para sure na okay lang lahat, at baka may special cough medicine na safe para sa pregnancy. A few of us mums dinaan lang ng paracetamol, lots of water, at honey, pero talaga best is to check with your doctor muna para peace of mind mo. Sending you feels, mommy, almost there na!
