Hi mama! Nakaka-relate ako sa anxiousness na yan, especially pag Letrozole + trigger shot cycle. So honestly, DPO 8 is still super early, the trigger shot takes a few days to fully leave your system, so any positive around now would be a real one, but a lot of mums I know got their first clear positive around DPO 10-12 instead. The cramping and heaviness you're feeling? Totally normal, some girls felt that, some felt extreme boobie soreness from DPO 5 onwards, and some felt nothing until way later, so it really varies. One friend actually needed four rounds before it worked, and now her baby is 8 weeks, so the symptoms don't always point one way or the other, which I know is frustrating. My honest take: your body might still be ramping up from the trigger, so maybe wait a couple more days before testing again, and definitely chat with your doc about what you're feeling, especially if the cramping gets intense. Rooting for you!
