I had sex on May 7th and I tested positive for ovulation once on Monday the 10th and again on Tuesday 11th, this means that I am currently 13dpo. According to the Flo app my period is due in 5 days. I have bought a clear blue ultra early pregnancy test and took one this morning as it says up to 6 days before period and it was negative, is there a high chance that I could be pregnant as I do not want to be?
