Uy, please see your doctor or call your OB agad, ha, especially when you're not feeling well at 21 weeks, kailangan nilang malaman kung ano talaga ang nangyayari. Hindi ako makakatulong dito ng tama kahit gusto ko, kasi pang-pregnancy ito at kailangan ng proper check-up para ligtas ka at baby mo. Wag mag-self-medicate na lang, mama, better safe talaga. Let me know how you're doing once you've seen your doctor, okay?
