I had unprotected sex on the 20th June, the last day of my period. I really wasnt bleeding at all though. 2 weeks later and i have had very light pink spotting that turned slightly brown the next day but got lighter and then just stopped. I am due on my period today or tomorrow but normally i get signs that im coming on before i do and I havent this time. I did an early detection test and got a faint line (ill post picture) and that was at night and then i did another the next late morning and got a negative result, but it was a digital one and wasnt an early detection one. Whats the chances im pregnant?
