Uy, alam ko yan! Sa 36 weeks, super normal na ang cramping at parang may discomfort sa lower abdomen, your body is really preparing na for labor, kaya ang Braxton Hicks contractions at ligament stretching ay normal talaga at nakakaabala. But just to be safe, especially since you're a first-time mom and gusto mo talaga malaman kung okay lang, i-mention mo sa OB mo sa next checkup para ma-confirm na it's just the usual pregnancy stuff at hindi something else.
