Okay my last period was Sept 12, 2006 I had sex Oct 3 and we used the pull out method I took a home test on Oct 9 I think that could have been earlier it was negative than on Oct 20 I had a brown red spot of blood only when I went to wipe after I use the bathroom, the next day is light but can almost by the end of the day fill up a panty liner. Do you think I am pregnant and I have been having lower back pains sore breast and headaches. And if I should test again when should I do that:confused:

Maybe you should go and have a blood test done. Home pregnancy tests often give false negatives.

I am sure you do realise that the "pull out" method is not a form of birth control and can still get you pregnant as easily as if he does not pull out at all.
