Hay, congratulations sa baby! Honestly, marami sa amin nag-color during pregnancy nang walang problema, pero since you're only 10 weeks pa, better to check with your OB muna bago gumawa ng decision, especially on the ship, para sure lang na okay for you and baby. A few of my mum friends who work abroad just waited til second trimester or did minimal touch-ups lang, so you might want to ask your doctor if natural or ammonia-free options would be safer for now. Kaya mo yan mama!
