Aw, congratulations sa baby mo! Honestly, it varies talaga, some of my mum friends got their period back after 3-4 months ng exclusive breastfeeding, while iba naman ay delayed until around 6-8 months or even longer, depende sa frequency ng pag-BF mo. The best thing is to talk to your OB about it since every mom's body is different, pero meantime don't assume you can't get pregnant while breastfeeding dahil may chance pa rin, lalo na if your periods haven't come back yet. Congrats ulit sa little one!
