Mama, please see your OB right away to check that bukol, seven months is important na i-monitor properly, especially if it's something new. Hindi ako makakapagsabi kung normal or not without a doctor looking at it, pero mas safe na confirm with your doctor agad. A few of us moms have had different bumps and growths during pregnancy, and lagi silang nag-check with their OB para sa peace of mind. Kaya please don't worry too much, but do get it checked soon, okay? Your baby and your health come first.
