Ay, 7 months na pala at may pain pa sa loob ng tahi, honestly, I'd check with your OB about that one, kasi sometimes may adhesions or something na pwedeng nangyari, especially after CS. A few of us mum friends had lingering soreness pero it was usually resolved by 6 months na, so better safe than sorry to get it checked out! May something specific na trigger ang pain, like certain movements lang or buong araw?
