Ay hindi talaga normal yan, mama, normal delivery cuts usually close within 2-4 weeks, so dalawang buwan is definitely worth getting a second opinion on! I'd really suggest going to another OB para ma-check properly kung bakit di sumusara, kasi meron namang possibility na may infection or hindi tamang healing, at ayaw namin bumukas ang pera mo without proper assessment. Ang kaibigan ko dati ay may similar issue at nag-consult ng ibang doctor bago mag-proceed ulit sa tatahi, so please don't hesitate mag-seek ng second opinion, ito ang kalusugan mo eh, dapat confident ka sa doctor mo!
