Opk +ve 2 kali???

Ooh ini happen to me jugak dulu! Dual surge boleh jadi, especially kalau cycle kita irregular or stressed. Some of the mums in my group mentioned getting two LH surges dalam satu cycle, second one boleh happen a few days before period or even after, tapi biasanya yang first surge je yang means ovulation happened. Since you're 4 days late with negative UPT, better check with your doctor lah, bisa ada hormonal imbalance, stress, or something else going on yang kacau-kan cycle. Don't stress lagi, sometimes our bodies just do weird things! Keep testing UPT if you're concerned, and let the doc take a look at your cycle pattern if it keeps happening.
