okay, so first off my period was a few days late. i had sex on new years eve. i got my period on new years day. my period was on and off the first day the second day was light and then the third day i had it it was spottin. i heard that my period carried it upstream. is that even possible? could i be pregnant? i've been bloated ive been tired and i have had to pee a little bit more then usual. i have been feeling nauses but no throwing up, no swollen breasts or nothing either. helppppp meeee!
