Ello, I Had My Period From The 27th To The

ello, I had my period from the 27th to the 2nd. And today when I went to the restroom I seen that I had spotting as if I just started my period. Which was very odd, but along with that I've had feet pain, back pain, I haven't been very hungry, I've been very itchy, I've had days where the smell of something bothered me. I'm not really sure if it could be my period starting again? Since they change every month or if I could possibly be pregnant, because I have had unprotected sex about 3 times since my last period but it seems too soon to be. But I'm not sure.
