Hey mama! Congrats on your pregnancy! So from what I've heard, Novaliches District Hospital's OB-GYN clinic runs specific days, Monday 8am-10am and Tuesday 10am-12pm, and you don't always need to book online; some mums just walk in during those hours, pero mas safe talaga to call ahead or ask around sa labor room kung may slots pa. Since you're 20 weeks, ngayon na ang perfect time to get checked and registered! As for pricing, normal delivery is usually around 5k-8k depending on room type, and C-section runs higher (maybe 15k-25k range), but honestly the rates change, so best mo na talaga sagutin ng staff nila directly when you go, they're usually helpful, though may patience kailangan haha. Tawagan mo lang ang main number nila to confirm the clinic schedule at matanong mo rin kung kelangan ng registration forms na i-prepare in advance. Good luck sa check-up, FTM!
