It's okay po as long as you've completely healed from your delivery, say 6 weeks after delivery if normal. If you're purely breastfeeding and hindi ka pa nagkakaperiod ulit in 6 months, hindi ka pa mabubuntis. Pero if nagkaron ka na kahit wala pang 6 months or mixed ang milk ni baby, may chance na pong mabuntis.
