Can a woman know if she is pregnant 4 days after sex?

Only by intuition - but sometimes that intuition is wrong. 3-12 days after conception, there can be a small amount of bleeding called implantation bleeding, but this is sort of rare. Home pregnancy tests aren't really fully accurate until she's missed a period (menstrual) about 2 weeks after conception.

If it's been 4 days since she had sex and she's claiming she's pregnant, she may have been pregnant before she had sex the 4 days prior.

Yes...I knew the next day...strong headache and pain on lower right side...

I had a friend once who had a dream of seeing a living, detailed event in which a sperm entered an egg. No one can tell me all dreams are meaningless. She had that dream a couple of days after having sex.

She was indeed pregnant. Some women can actually feel the energy of the egg beginning to change. I think it completely depends on the sensitivity of the woman.

I really don't think so. The earliest a pregnancy test can tell you is up to 5 days before your missed period. So let's say you're supposed to start on the 29th of the month, you should be able to take the right brand of pregnancy tests on the 24th.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
