Ahhh 15 weeks, that bloated feeling is SO normal lah, second trimester doesn't automatically flatten everything, hormones are still doing crazy things! The headaches and fatigue are classic jugak at this stage, your body is working overtime growing a baby, so cut yourself some slack dengan chores, can ask hubby or anyone else to help a bit. A few of us mums noticed it helped to drink more water, rest when you can, dan kecil-kecilan meals instead of big ones, the bloating memang annoying tapi should improve soon. That said, if the headaches are really bad or you're worried, worth checking in with your doc just to be sure everything's good, okay?
