Ah anak, any cramping during pregnancy is something you really need to check with your doctor right away, hindi dapat ma-guess yung ganitong bagay, especially in the early weeks. I know it's scary, pero mas okay kung ma-clarify agad ng doctor kung normal lang siya or kailangan ng extra care. A few of my mum friends din nag-experience ng cramping early on, pero each pregnancy is so different, some was okay, iba hindi. Better safe than sorry talaga, so please make an appointment or call your OB ASAP. Thinking of you, mamsh!
