Haha sis you're not alone, maraming mommas namin ang same experience during pregnancy, it's totally normal because of the hormonal changes! One of my mum friends said the same thing, parang she became a different person pag pregnant, tapos after delivery biglang nag-disappear ulit, so she was relieved pero nag-miss din siya ng that phase haha. Honestly, best approach is just to talk to your hubby about it, kahit nakakahiya, most partners understand na it's just pregnancy hormones at not something you can control, at actually marami sa kanila ang napapasaya talaga na makita ang wife active again kaya go lang! Seven months is still the sweet spot para mag-enjoy, so don't feel too self-conscious, it's one of those weird but beautiful pregnancy things na mawawala rin after. Fingers crossed bumalik din after mo mag-deliver, pero kung hindi kaya, at least alam mo na it's hormonal at may logical reason!
