Can you still be pregnant with a negative test 1 day before your period is suppose to start? My husband and I had sex on the 13th, which was my ovulation day, and the day after. I've had light bleeding for the past 5 days but I know it's not my period. My period has been very regular and this has been super light and started a week before I'm suppose to start my period. I thought it was implantation bleeding, but today it is a little heavier, but still not heavy enough for a period. it's still a day before I'm suppose to start. I've been having all the pregnancy symptoms (nausea, sore breasts, headaches, mood swings, very tired all the time, frequent bathroom breaks the whole 9 yards) I started cramping earlier this week before I started the light bleeding. And if I'm thinking right over the past 5 days it's gotten a little heavier each day. Is there still a chance of a pregnancy? Or am I not pregnant?
