Mamsh, yan talaga ang pregnancy hormones doing their thing, totally normal! 4 months in, ang emotions mo ay all over the place kasi ng progesterone at serotonin changes, kaya yung sudden tears, overthinking, at low confidence moments ay napaka-common, lalo na during the second trimester. Pero since feeling mo talaga na iba ka na, na nag-shift ang mood mo in a way na nakakaaffect ng daily life mo, better to chat with your OB about it, hindi ka O.A., promise, and they can help determine if may postnatal depression na signs na or pure hormones lang. Huwag ka mag-alala mag-open up sa doc, kaya namin yan!
