I am trying to get pregnant and I haven't taken my contraceptive pill since my last period. I bought an ovulation kit and detected by 2 most fertile days. I had sex 2 days before the fertile window and then on the most fertile day. ovulation occurred 2 days ago. When can I find out if I am pregnant..? I have just carried out a pregnancy test and it is negative is this because the chances are I am not pregnant or is it that I have taken the test 2 days after having sex on my 2 most fertile days.....??
