It depends , you can get implantation bleeding around conception , if it is extremly light or brownish in color and happens for a no more than a couple days this could be true my freind got that and then found out she was pregnant. Are you having cramps , are your boobs sore , feeling sic , unusually tired anything out of the norm , if your period doesn't show go ahead and test and if you are still late then go to the doctor and due a blood draw , anytime there is unprotected sex there is a chance of pregnancy you don't have to be ovulating , sperm can live up to five days inside the uterus and three days outside so thats quite a window of oprotunity , you can pretty much get pregnant anytime in that month even when your bleeding. I am ten weeks pregnant with my first and by my caculations I conceivied right after my last period even though I don't ever ovulate till the middle of the month , I got a postive read on my pregnancy test two days before my period.

If you had your normal period, even if it was early, you are not pregnant. If you are concerned, take a pregnancy test.

If you do not wish to become pregnant, use birth control.

Good luck.

It is not clear from your post whether you are trying for a baby. If you don't want a baby I suggest using a form of birth control next time you have sex otherwise you are at a high risk of getting pregnant.

i had cramps like two days ago and ive been feeling sick when I move alot of after I eat. Ive been really tired, more then usual.

You got your period....What are you worried about? Unless of course it was very light pink and didnt last long. If it was normal flow and lasted as long as usual then your not pregnant.
