Also, on top of what others have said I have noticed that you have said it 'usually works'. Does that just mean that dring this time you haven't got pregnant? I take it it does. You don't get pregnant every time you have unprotected sex (and the withdrawal method is NOT a form of contraception. It is NOT reliable). There is a specific time window in which you can get pregnant (which can change between different cycles as not all are the same length even ifyours usually are) and at other times you can't. There is no way to know for certain whether or not you've ovulated (unless you seek tests at a doctors) though there are indicators and so you don't know if it's just been the timing each time. Even if you have unprotected sex at the right time, even presuming the guy has a really high sperm count and healthy sperm (which to be honest a lot don't) then nowhere near everyone gets pregnant and if the sperm and egg do fertilise this doesn't necessarily mean this will implant into the uterus and even if that does then it doesn't always mean you have a pregnancy resulting. That's just showing that it is down to pot luck what you're doing and depending how long you've been doing it it may just be that you're incredibly lucky (if you're not trying to get pregnant) that you've not.
You need to take a test. They are best taken first thing in the morning when the hormone level will be at it's highest. If that comes out negative then wait a few days and if your period still hasn't come then take another as it may be the first didn't pick up the hormone because there were too small amounts or it was too early for your body to be releasing it whereas the 2nd being done a few days later will tend to have higher levels of hCG (the hormone they test for) in the urine compared to the previous time as there will be more going around your bloodstream and entering your urine then.
If you're not prgnant then it may be that you're just stressed (sometimes the worry that you may be pregnant tips it over the edge and the worry delays it), that it is naturally a longer cycle, there is a bit of a blip in your hormone levels that will sort itself out or could also be to do with a change of diet or lifestyle.
If you are pregnant then whatever you want to do you need to see a doctor ASAP. If you're not then I'd advise you strongly to go to the doctors and discuss methods of contraception. Condoms (apart from 'sheep-skin' latex-free ones) are the only type of contraception that also protect against most (not all) STDs but then if you're both 'clean' and only sleeping with each other then that will not be a problem. Other common forms are the pill (of which there are several types) which you take daily, the injection which you generally have every 8-12weeks depending on the type, the implant (Implanon) which gets inserted via very minor surgery into your arm and this lasts for 3yrs and is the most reliable form of contraception at the moment, or, usually reserved for people who have already had children but not necessarily, you can also have the coil fitted which gos into your uterus and releases hormones which prevent pregnancy and it also stops implantation. There are also other types available but those are the most common. As well, if you're not wanting to get pregnant using these alongside a condom is also the best way and gives the most protection but any sort of contraception at all is much safer than what you're doing right now.
