Congrats sa baby mo! Alam ko yan, yung evening sickness is super common sa first trimester, lalo na around 9 weeks, kaya hindi ka nag-iisa dito. A few of us moms went through the same, grabe talaga ang gabi kaya minsan I'd eat small, frequent meals and avoid anything too oily or heavy before bedtime, pero honestly, iba-iba talaga from person to person. Since you're having both stomach pain and vomiting together though, mas better na i-check mo with your OB para sure lang na lahat is okay, better safe na, especially first time
