Yes. Sometimes a pregnancy test cant detect it that early but you could still be!!
i came on my period 7 days early can i be pregnant
the "period"you thought you were having could be implantation bleed so yes you could be pregnant. just do a pregnancy test.
Not if you haven't had sex since your last period.
If you had a period after you had sex, you're not pregnant. The uterus is shedding its lining, which, if you were pregnant, it would keep to nourish the embryo.
If your period was heavy or like usual then its not likely that you are pregnant.
Of course you can be anytime you have unprotected sex you may become pregnant.
Yes if after your period but if seven days before your period you will not become pregnant...
take a pregnancy test
