Aww mama, understandable na worried ka kasi different ang experience mo with your second, pero since walang spotting at 7 weeks, that's actually a good sign! Buti naman talaga na mas observant ka ngayong second pregnancy, kaya better check in with your OB just to be sure everything's okay, especially pag persistent yung pain or kung may changes pa, wala naman mawawala sa quick checkup, diba?
