Hi mama! Yan talaga ang challenge ng desk job, parang ang katawan mo ay waiting lang haha! A few of us tried staying active kahit nasa office, and honestly, movement really helps: take walks during lunch (even just around the building), try squatting or hip circles while sitting, and if you can, rock back and forth or use a birthing ball at home in the evenings. One of my mum friends swears by just changing positions frequently throughout the day, sitting differently, standing, swaying, kasi parang tumutulong sa baby na mag-settle better sa pelvis. The key is consistency lang, hindi extreme exercise; your body will know when it's ready. That said, definitely check with your OB about what's safe specifically for you, especially kung closed pa cervix mo, they might recommend timing or other things based sa personal situation mo. You're so close na!
