Ay, spotting during pregnancy can mean a few things kaya better check with your OB agad para sure, lalo na kaya nandito ka na nag-aalala, pinkish spotting usually sounds lighter than period bleeding pero important talaga i-confirm especially this early sa pregnancy. One of my mum friends had the same thing at first at everything turned out okay, pero seryoso talaga ang check-up para peace of mind mo at makita kung ano exactly ang happening. Hope it's nothing serious, but don't wait, call your doctor na po!
