Ay alam ko yan, first time kasi talaga nakaka-paranoid! The white discharge is totally normal, yan lang ang gamot na lumalabas, hindi infection, so wag mag-alala doon. The pink liquid in the morning, na-observe din ng iba na nangyari, usually just because ng slight irritation from the suppository itself, lalo na if you're sensitive sa area.
Some mums namin noticed mild cramping or slight burning feeling sa first few days, which is annoying pero temporary lang, it should settle after a couple more days once your body adjusts. If the discharge gets really heavy, super itchy, or the burning gets worse instead of better, then definitely text your doc agad, pero from what most people share, yan yung normal side effects lang ng Vagilin. Good luck, mama!
