Aaa normal je, don't worry! Benang yang dah masuk kulit mmg boleh terasa macam ada foreign object sikit-sikit, especially kalau area dia still sensitif masa healing, boleh ambil few more weeks sampai completely soften and blend dengan skin. Aku pun rasa gitu masa pantang, benang terasa macam ada, tapi it dissolves on its own. Tapi sebab you're worried, maybe just mention to your gynae during check-up or just text clinic to confirm, tak ada salah, dan sure dia boleh reassure you quickly je. In the meantime try not to prod it too much (I know, hard resists ), and if suddenly jadi merah, bengkak or ada discharge, then boleh call la. You're doing fine!
