Hi, am 19 yrs old. I had unprotected sex 5 days before my period. On the following tues after sex i started something like a period only it was brown colored then on wed i had a light brown mixed with light blood then thurs just spotted fir spotted then sat i am still spotting brown. Is there any way possible i could be pregnant? How soon can i test if i had unprotected sex 9 days ago...this was the strangest period i ever had and for some reason i had a really weird feeling.
