Ooh yes, a few of us did blood test awal-awal! Honestly, you can detect HCG through blood test around 6-8 days after ovulation (so like 8 days before your missed period), way earlier than urine tests, that's why banyak mummies yang nak confirm ASAP go for the blood route. I did mine 4 days before my period and it showed up clearly, tapi depends on your cycle and HCG levels juga. Best thing is go to a clinic or lab and ask them, they'll know exactly timing, and the doctor can explain better based on your situation!
