Oo normal yan, sis! Yan ang Braxton Hicks contractions, practice contractions lang ng katawan mo para sa actual labor, kaya walang alalahanin. A few of us expecting moms noticed the same thing around that week, especially kapag tired or aktibo kami, pero mas lumalala pag dehydrated or stressed, so make sure you're drinking lots of water and resting properly, pero kung mabigat yung tightening, may bleeding, or sobrang sakit, definitely message your OB na agad para sure lang!
