Aiiii sayang, UPT yang makin pudar after 8 weeks tu actually normal je, the hormone levels dah stabilize dah so the test lines won't be as dark anymore. Tapi tu cramping and discomfort you're feeling, even if it's mild and not frequent, please see your doctor or go to your antenatal clinic soon, ya? Better safe than sorry lah, especially at this stage. Pregnancy symptoms can vary for every mom, tapi a quick check-up with your healthcare provider will give you peace of mind and confirm everything is okay. Sending you lots of hugs!
