How many days after having sex should a blood pregnancy test be accurate?
I had sex on March the 9th and had a blood pregnancy test yesterday (April the 10th) and it was negative. Is this accurate?
I wanna add that I took the morning-after pill and have been under the most terrible stress u can ever imagine. I guess this is why my period is late.

some sevenother 21 30 days
I believe that it is the 1st week after a missed period. I was told that is when you want to take the test
It would have shown up in a bllod test by now.
I read that a blood test shows results up to 6 days after conception and very rarely are blood tests inaccurate. I also had one done and it was correct. A few days after the test my period started. Hope this helps you.
I think it is accurate. I had to have fertility treatment in order to get pregnant, and had to go for blood tests the very day after having artificial insemnation. On all 3 of my pregnancies, the blood tests done the following day proved to be totally accurate.
yes its accurate. blood test are usually accurate within 3-5 days of conception..stress is more ikely the reason for your period beign late…it doesnt take much to mess up your cycle
I know this to be true. A blood pregnancy test will show your pregnant seven (7) days after you concieve.
Trust me I know.
You could take a at home pregnancy test and it should show up by now if you are late. A pee test will show you’re pregnant about 5 days before a missed period maybe a little sooner than 5 days.
If it didn’t show up in your blood then you are not pregnant. Those are more accurate than a pee test.
REMEMBER IT SHOWS UP IN YOUR BLOOD 7 DAYS AFTER YOU CONCIEVE……….GOOD LUCK!!!!
