At 10 days after ovulation a blood test can sometimes pick it up, but home kits are often too early. My doctor said wait till after the missed period for a urine test to be reliable. Testing too soon mostly gives false negatives.
Home kit at 10 days is usually too early, hcg is still low. A blood test detects it sooner if you really cant wait. Otherwise just give it a few more days for a clear result.
I tested way too early once and the negative broke my heart, then later it was positive. Dont do what I did, the waiting is torture but worth it. Blood test is the surest if you must know now.
