Ay, LYNDEL is a hormonal contraceptive so common side effects from oral pills in general are spotting, nausea, or mood changes, pero honestly, ang experience namin ng kaibigan ko varies, some had walang problema agad while iba adjusted after 3 cycles pa lang. Since you're postpartum, best talaga mag-check with your health center doctor kung ano exactly ang side effects you're experiencing kasi important na ma-monitor especially if you're breastfeeding pa, then they can adjust if needed or i-recommend ng ibang option!
