Ay sis, marami akong kaibigan na naka-experience nito around 8 weeks! Yung parang sudden stabbing tapos mawawala agad, that's usually lightning crotch or round ligament pain, which is super common sa early pregnancy as everything's stretching pa lang. A few of us swear na it's nothing to worry about most of the time, pero if it's happening a lot or you're getting spotting with it, definitely tell your OB agad kasi it's better safe than sorry. The good news is usually tumatagal lang ng seconds tulad ng naranasan mo, at it just means your body's adjusting! Still, mas mabuti pong i-mention sa doctor mo during your next visit para ma-confirm lang na lahat okay with the pregnancy. Praying everything's smooth sailing for you, mama!
