It is possible that you are expierancing implantation bleeding, but it is entirely too early to take a test. So you are in the famous 2 Week wait. Crossing my fingers for you! Please keep us posted!
ovulation was 3rd-8th. cycle dosnt start till the 21. had sex on the 1st, 3rd, 4th and the 7th. i know you can ovulation bleeding, but i have never ever had bleeding during or after ovulating.
When was your ovulation date? Spotting may be a sign of pregnancy, but it could also be your cycle starting. Take a test as soon as you miss your next period. Do you have other symptoms? Good luck.
