Mama, please check with your OB soon, especially since you're having tightness in your belly, trouble swallowing, at walang gana to eat, kasi yan ay kailangan tingnan ng doctor. These changes need proper assessment, hindi lang siguro online.
You're doing great carrying baby at 7 weeks, at nandito lang kami to support you, pero yung peace of mind na makukuha mo from your doctor ay mas importante talaga. Kaya na natin ito together, mama!
