Ay, first trimester talaga ang most delicate kaya better check with your OB muna bago mag-travel, kahit short distance lang, you want to be sure na okay lang for your pregnancy stage! A few of my mum friends said their doctors nag-clear them for travel sa early weeks, pero depende talaga sa condition mo, if may spotting or complications, kaya mas safe na magpa-check lang. The Laguna-Manila trip shouldn't be too taxing if your doctor says go, pero make sure you're comfortable, hydrated, at may rest stops, di ba?
