How soon can you tell if you might be pregnant?

Question

On November 21, 2006 Tuesday my boyfriend and I attempted sex, but we kind of freaked out and waited a week later, November 28, 2006 Tuesday we finally did it, but witha condom. The attempt on the 21st was unprotected and he only had two inches in. There was no blood or anything afterwards, so I guess either the dancing stretched the hymen like crazy or I was raped & don't remember. But I started noticing changes in my breast size on November 27, 2006 Monday. What I want to know is if that is a good sign of being pregnant? I know the precum can get you pregnant, so that's why I'm worried - although small chance of that but still....
I researched on Wikipedia before noticing my breast change and noticed that the same chemical that causes one to be tired after sex is the same that produces milk or something. So I'm wondering if it's only that.
Also, I'm seventeen years old and there's a possibility that I was growing and noticed it only after I had sex.
Please help!

Answer 1

Certain over the counter pregnancy tests can tell within 1 day of a missed period that you are pregnant. However, a blood test can tell before you miss your period. Of course that would mean going to your family doctor and I doubt you want to do that. The only truly reliable way to tell you are pregnant is a missed period and positive pregnancy test. Every other symptom of pregnancy is easily imagined, attributable to other issues (hormones, illness) and different for every woman. Do not base your panic attack on those symptoms alone.

Answer 2

Well take a test 5 weks after you last period, or 1 week after missed. You should be able to tell then. Good luck. Im 19 and expecting my second kid. I think having kids young is the best, as long as you are mature enough to handle it.

Answer 3

It takes about two weeks for the homone to be able to register on a pregnancy test.

Answer 4

no more period
