Honestly, same concern ko dati kaya I get it! I've tried pills (nakakagain talaga for me, even the low-dose ones), so I switched to the IUD at 28 at never looked back, walang hormones kaya no weight gain, super convenient, at effective for years. But if IUD feels invasive, maraming momshes dito swear by the implant (the rod sa braso) or condoms + fertility tracking para sa peace of mind without the hormonal side effects, it's really about what feels right sa body at lifestyle mo. The best one honestly is what you'll actually stick with, so maybe chat with your OB about your weight concerns specifically, kasi alam nila kung ano ang gentlest options para sa'yo.
