Oo normal lang yan, marami sa amin na nakaramdam ng body aches at parang may lagnat after the 2nd dose, it's just your body building immunity kaya don't worry, hindi yan makakasama sa baby! Best thing is mag-rest ka, drink plenty of water, and if the aches persist or you get a high fever, message your OB para peace of mind lang, pero honestly from what I've seen sa mga kaibigan ko, naglipas lang ito in a day or two at ang babies namin ay perfectly fine.
