depend on your ubo. may phlegm na ba? what color? if there is then need to talk to OB. I was on high dose pure vit c when i was pregnant. Never ako nagka ubo or sipon.
when I told my OB kapag inuubo ako , sobra sakit ulo or sipon , MORE WATER Ang sinasabi , nun naulit ulit inom na daw ako biogesic BUT BETTER CONSULT ON YOUR OB PO
More water lang sabi ni OB and twice a day ako pinagtatake ng Vit C.
inom lang ng water na may lemon....or kalamansi,mie.
