Uy, yes normal yan sa breastfeeding, lalo na if exclusively breastfeeding ka pa, maraming first time moms namin dito ang walang regla for months dahil sa breastfeeding hormones, really! But since June na talaga and negative ang PT, best to check with your OB lang para sure, kasi sometimes it takes a bit ng time para bumalik ang cycle or may ibang factors na need ma-rule out, mas makakatulog ka ng mahimbing pag alam mo na lahat okay!
