Aw congrats on your pregnancy, mama! Yan talaga ang first trimester, sobrang normal yan, a few of us went through the same thing, parang ang body mo ay doing overtime kaya napakapagod at emotional ka na sa lahat, haha. I'd suggest you mention all of this sa OB mo sa next checkup though, just to make sure everything's okay and maybe they can give you tips on managing the fatigue and mood swings kasi bawat pregnancy is different. Drink plenty of water, rest when you can, at don't be too hard on yourself, your hormones are going crazy right now, ito lang yan!
