I had sex on august 1st which was day 4 of my period and cycle, I used condom and the pull out method. I also had sex on day 18 aka august 15th with the same protection. I had no visible leaks or slips but I am now day 22 of my cycle and have red streaked clear discharge, I took a pregnancy test at 1:30 pm after not peeing for abit and it was negative.. but could it be a false negative? Should I be worried? Any help would be lovely, I'm desperate
