Uy, congrats mama! At 5 weeks, honestly sobrang unpredictable, some days I felt nothing, tapos biglang nausea out of nowhere, parang laging gutom pero takot kumain, haha, and my boobs were SO sensitive na masakit kahit tumayo lang ako agad from bed. A few of us moms noted na around that time super weird din ang sense of smell namin, like biglang hindi na kami kayang amihan yung coffee or ilang pagkain na dati gusto namin. Every mama is different though, so kung may unusual symptoms ka na worried ka, mas maganda i-check with your OB para peace of mind, buti lang kasi sila ang makakaalam kung normal for you yun or hindi!
