Aw mama, 2-3 weeks is quite long talaga, lalo na at may nanana pa, normal wound healing is around 1-2 weeks lang kaya I'd really suggest checking with your OB sooner rather than waiting next month, kasi baka need ng topical antibiotic or may minor infection na. Madali lang mag-request ng earlier appointment para peace of mind mo, at mas maayos i-manage while you're preggy pa. In the meantime, keep the wound clean and dry, change dressing regularly, at avoid touching it with dirty hands, hoping it heals faster para sa 'yo!
