How soon can I test? Well, first you gotta know how the test works. Briefly: the home pregnancy test (HPT) works by detecting a hormone called human chorionic gonadotropin (hCG.) When an egg is fertilized, it takes about 6 to 12 days to implant in the uterus, and then it begins to secrete hCG. It takes another day or two for enough hCG to build up and make its way into your pee. So, generally speaking, the earliest you can expect a positive HPT is 8 days past ovulation ("DPO") and the latest would be about 16 DPO. It is possible to get a positive test earlier or later, but not as common. In my experience, if you use a sensitive "early" test (anything that detects 25 mIU/mL of hCG or less) you can test around 12-14 DPO and feel reasonably secure with your results (the later you test, the more secure you can feel in its accuracy.)
If you do not chart or monitor your fertility in any way, and you think you may have conceived, you should wait 19 days (or longer) after having sex to test. Why 19?! Sperm can live approximately 5 days in the proper environment; if the sperm managed to live until you popped an egg, the actual conception could have taken place several days after the sex act that got the sperm there. To make sure you're not testing too early, assume the sperm had very long lives (5 days is considered a very long sperm life) and that conception occurred then. Then allow 14 days for the embryo to implant and develop enough hCG to show up on a pregnancy test (96% of pregnant women will test positive by then.)
Note: some HPT's say "test 5 days before your period is due!" or some such thing. Please note they are assuming a textbook 28-day cycle, with ovulation on Day 14. "5 days before your period is due" thus really "translates" to 10 DPO.
Essentially, you should remember that your high school biology textbook was WRONG. NOT all women have 28-day cycles and NOT all women ovulate on Day 14. For more info on this type of thing, see the Fertility Info section.
Here's an example. This is the textbook-perfect 28-day cycle with ovulation occurring on day 14 (in pink.) 10 DPO and later are reasonable days for testing (in green.) This is the cycle the HPT companies have in mind when they say "test 5 days before your period is due!"
Well, not everyone's body works this way. Here's another 28-day cycle-- but this one has ovulation occurring a little bit later, still well within the normal range. Watch what happens to your (green) testing opportunities!
All of a sudden, "5 days before your period is due!" is way too early for you to expect a positive test! (I tend to ovulate later myself, so by the time the "gold standard" of testing at 14 DPO is applicable, my period is already 3 days late! I needed to use an "early detection" test on the first day of my missed period. A "regular" test would probably have been negative-- even though my daughter is living proof that I was, indeed, pregnant ;)
Of course, it works in reverse, too. If you're an early ovulator, you're lucky! Check it out:
In this scenario, you could test even sooner than 5 days before your expected period.
Ultimately, it's important to remember that implantation is a variable thing. You may be able to detect a pregnancy very early on, but then again, you may not! If you can't, don't despair.

It's probably to early to test wait a week and test.. as for your boobs yeah they very well could feel that way while you are pregnant but they could also feel that way before you get your period to... I would say the best thing to do is test now if you really feel the need to and if it is negative wait a week and try again if still neg and you feel you are preggers call your doc for a blood test.. best of luck to you

It would be nice to indicate when your LMP was. That would help us determine if you should take the test or not. Im assuming because of the question, you should have missed it. The breast symptoms was my first symptom in knowing I was pregnant. Not sure by how many days your cycle is missed, so I would recommend taking a HPT at least week after missing it. Blood work can be done even now to get a definite answer.
Good Luck!

Yes, your breasts will feel tender if not extremely tender. They will feel heavy and slowly (obviously) start to grow as your body begins to prepare for the child. I think you should take the test. And like others have said if it shows up negative then take another one. With over the counter tests you're never 100% positive because they have their flaws. But if you get two that say yes or two that say no and you keep feeling your body changing, go see your doctor and have them give you a pregnacy test. Best of Luck!

Well, if it's 5 days or less away from your period, go take the test. Any longer than that, you might as well just wait. Especially if money is an issue, like the other user said. I can't think of the test, but it does up to 5 days before your period starts.

take a test to be sure when you are about a week late.
when I took my test I had my regular pms symptoms (sore boobs, moody, tired, etc etc)
I only took the test because I was late--there was no other tip off's.
most pregnancy signs dont start until you are at least 5-6 weeks along. & that first one is usually the morning sickness
& some people get the morning sickness starting at 8 weeks.

It would probably be a good idea to get a test before you go out. Sometimes alcohol damage is done to the baby before the woman even realizes she's pregnant. It seems to me your period is just irregular if you've been using protection and it's been late before. But it's better to be safe than sorry. Remember your baby eats and drinks everything you do.

Well every women have different symtoms but yeah sometimes they do feel heavy. Are you missing your period??? I don't think it hurts at all if you take the test. I think you should do it because if you are you should start taking care and see a doctor. Well good luck. Also if you haven't miss your period I think you can wait a little longer and see if you get your period or if you get more symtoms. It just depends on you.

Yes and Yes. Tenderness in the breast is an indication and you can take the test if you are late. You can take the test earlier but I would wait until I was at least one week late. Be sure to follow instructions on test carefully.
