Wah, scary kan first time balik camtu! But honestly, bleeding lepas pantang especially during intimacy is quite common lah, a few of us mums had the same thing, and yes, breastfeeding can make things drier down there sebab hormones. Since your episiotomy scar dah okay and takde sakit, it's likely just that, tapi sebab ni first time lepas bersalin best you check with your gynae just to be safe, kan, they'll confirm everything healed properly and can suggest some moisturiser or lube untuk comfort.
