Oo momshie, totally normal yan! Pag exclusive breastfeeding talaga, ang prolactin hormone namin nagsusupress ng regular periods kaya irregular or wala pa rin ang mens, lalo na hanggang 1.5 years pa lang si baby mo, a few of us moms namin dito ganyan din, some didn't get their period back until after 2 years of breastfeeding. Since you got it in January though at medyo mahabang flow, siguro ang body mo starting na mag-adjust, pero hindi guaranteed pa na regular agad this month kaya don't stress if wala pa, the hormones are still finding their rhythm with the breastfeeding. Since nag-condom kayo, you're good sa pregnancy worries, pero if you're really concerned or the flow becomes super heavy or painful next time, check with your OB para peace of mind lang!
