technically, there is no "safe zone" in regards to fertility. All in all, the chances are quite low that you became pregnant. I would wait until your time of the month and if you're late, then take a pregnancy test.

In the future, please, please, please use protection. Pregnancy aside, there are a myriad of different diseases that you don't want to have and some of them are incurable. Please use a condom. If you are having sex, I would also recommend that you go to the doctor to get a pap smear and check up. These are vital to maintaining your health and finding problems before they can threaten your life. At your checkup with the doctor, you can talk to him/her about getting on a reliable method of birth control. It takes about a month for most birth control methods to be most effective so don't think you can discontinue using condoms on the first day of getting the pill.

Peace,

You would have to wait untill you miss your next period to see if your pregnant or not. If you have a normal 28 day cycle then you still have a couple weeks before your periods even due, so a pregnancy test now wouldn't show accurate results
