Pregnancy.

Oo, normal lang yan sa maraming pregnant moms, lalo na sa first trimester dahil sa hormonal changes, pero if it's really severe or may iba pang symptoms like vision changes o swelling, mas better talaga magcheck agad sa OB mo para sure lang. A few of us sa mommy group namin experienced headaches especially pag dehydrated or stressed kami, so make sure kumakain ka ng balanced meals at umiinom ng lots of water, pero para sa peace of mind mo, let your doctor know pa rin especially since first time mo.
