So I had sex on the 20th of November. We used a condom most of the time and then near the end took it off and used the pull out method. I watched him finish outside of me. However, 5 days later while using the bathroom I have recognized yellowish-creamy colored discharge then while wiping I saw some faint blood but it went away. I should be starting my period before the 28th but I can't remember exactly when it should be. Today on day 6, I have been cramping like a period but no blood ! I'm FREAKIN out. Could that faint blood and cramping mean implantation? Could I be pregnant? What does implantation bleeding look like and when do you typically get it? And if my period doesn't come is that a for sure sign of pregnancy? I need some experienced answer please!
