Wah, I totally understand that paranoia, using two methods at once still leaves you second-guessing yourself every month, so it makes sense to look into something more reliable! A lot of mums I know have switched to the hormonal IUD (like Mirena) or the copper IUD postpartum, the hormonal one can actually lighten or stop your period, which many find a bonus, while the copper one is hormone-free if you prefer that, though some said their flow got heavier initially. My friend went to a gynaecologist at Mount Elizabeth and said the insertion was uncomfortable for a day or two but after that she totally forgot it was there, and fertility returns pretty quickly once you remove it. Some mums also do the mini-pill (progestogen-only), especially if still breastfeeding, though a few mentioned spotting and remembering to take it at the same time every day can be stressful. Side effects really do vary from person to person, some had no issues at all, others noticed things like breast tenderness or mood changes, so it's a bit of trial and see. Definitely worth having a proper chat with your gynaecologist or polyclinic doctor to weigh what suits your body and lifestyle best! Are you still breastfeeding, by the way? That might narrow down which options work better for you right now.
