Oo normal yan, mamsh! Every pregnancy is different, ako sa first ko, parang walang tyan pa rin ako until around 20-22 weeks, tapos biglang boom lumaki haha, habang ang kaibigan ko nakita agad yung bump. Basta comfortable ka at walang cramping or spotting, you're probably fine, pero best to mention it sa OB mo sa next checkup just to be sure lang, they can confirm everything's on track. How are you feeling otherwise?
