Ay mama, kaya mo yan, almost there na! Those tightening sensations you're feeling sound like Braxton Hicks, especially at 37 weeks, totally normal, pero since they're happening every evening, best to mention it to your OB on Saturday para ma-check kung may changes na sa cervix mo. About baby's weight, 2.8kg ay okay pa naman at may time pa kayo mag-gain together, but your OB will guide you better kung kailangan talaga ng specific diet adjustments para ma-reach ang target weight, a few of us had similar situations at sinabihan lang kami ng doctor kung anong foods to focus on, hindi forced eating lang. Take it easy with work if you can, rest more in the evenings, at hydrate well, ang stress at fatigue lang talaga ang nag-trigger ng frequent contractions sa aming mga kaibigan. You're so close, mama, excited na rin kami para makita si baby girl soon!
