14 days ofter my period, during my ovulation time, I had intercourse, unprotected. The day after by boobs have been really tender, and sore, and it's been a week and still sore boobs. I have not yet started my period, but it is not due till next week. I took a pregnant. Test and it was negative, could I still be pregnant? What other signs should I look for, and when is the best time to take the pregnant. Test?

You could, yes, wait till after you've missed your period and take another test.

Oh come on, your period isn't even due yet, you can't even take a test yet, yet you think someone online can magicallly know whether you are pregnant? There is a psychic section, ask there.

If that was the only day you had sex during this cycle, you would not notice breast tenderness due to pregnancy.

IF an egg was fertilized, it takes 7 - 10 days before it can implant. After that, you may notice symptoms, or you may not for several more days.

Wait until you are at least 1 day late before you test.

It sounds like you're purposely trying to become pregnant, so I hope you're on prenatal vitamins with folic acid. Prenatals should be in a mother's system BEFORE she falls pregnant to avoid neural tube defects.

It is hard to tell because alot of pregnancy symptoms imitate pms symptoms! wait another week or 2 and take another test..or go to a clinic and get a blood test! good luck!

Oh and as for the signs? It is different for everyone..I believe some of the first signs (though not in everyone) could be frequent urination, breast tenderness, and absence of your period!

You would not get pregnancy symptoms the day after you had sex.
