Hi everyone. I had sex 3 weeks ago today but we used a condom! I have no clue if it broke, if it was out on properly etc as it was very bloody dark! Today I am 6 days late on my period which is very unusual for me, I am never later than a day! If anything, I usually come on early that I expect! I have taken pregnancy tests and they've all come back negative. Is there any chance I could still be pregnant, but it be too early to show up on a test yet? I'm only 20 so I'm pretty inexperienced. Usually I get quite ill with cramps etc, and am very sick the day I'm due on but I've had none of that
