I got my period on Nov. 13th and it lasted 6 days, ending the 19th. My fiance and I had unprotected sex on the 20th and he finished inside of me. Since the 20th until now, we have had unprotected sex but have used the pull out method. The last 4 days I have been ovulating or what I think is ovulating. I m curious of when in your cycle your supposed to get implantation bleeding , if I were to get it. And If I were to be pregnant, would I be ovulating at all if the unprotected sex was shortly before my ovulation was supposed to occur? Oh and if I were to be pregnant, what is the earliest I could take a home pregnancy test and get it be positive?
