In how many days can I trust the pregnancy test?

What is the quickest working and most accurate home pregnancy test, and what is the cost. Don’t tell me to go to my doctor and get a blood or urine pregnancy test, that’s not an option. Thanks.

I have been told that a pregnancy test 2 weeks after having sex can be accurate. But *how* accurate? If it comes back negative, what are the chances of pregnancy? Like, if my g/f and I had sex on the night of October 31, how accurate would a pregnancy test administered on November 15 be?

I am currently on Seasonique birth control, I was supposed to start my period on Sunday, it is now Wednesday. I took the pregnancy test and it was negative and I am assuming it is too early before my missed period to know whether it is accurate or not.. If anyone has any insight please let me know…. Will a first response test work better?

How accurate is a urine pregnancy test when taken after 3 weeks of intercourse and in the placebo week?

My cycle is 28 days. I started spotting on 8/31 and my actual period started 9/2 therefore this month im not sure if my period is going to come sunday 9/28 or tuesday 9/30. Can i take a pregnancy test tomorrow morning and get a accurate result? Has anyone gotten an accurate result a week before their scheduled period? Thanks for the answers in advance.

My friend had a blood pregnancy test done 7 to 8 days after possible conception and the result came back negative. She is still having pregnancy symptoms. She asked the lady who gave her the results and the lady said that the test should not be done until atleast 10 days after conception to be most accurate. How accurate is a pregnancy blood test 7 to 8 days after conception? Thanks in advance!
