There are many reasons why your period may be late. You say that you are irregular, anyway, and you may well find that your period starts in the next day or so. It may even have done so by the time that you read this answer!
However, stress is one of the most common factors that delay the onset of your menstrual cycle. If you have been experiencing an unusual amount of stress at home or work recently then this can affect your period. Of course, this can be related to the fact that you are concerned that you may be pregnant. It can be a vicious circle!
Firstly, you need to reduce the stress in your life as much as possible. I cannot comment on the other issues in your life but can recommend a course of action relating to your pregnancy tests. I would certainly visit my doctor and ask for him to conduct a pregnancy test. This will give you a definitive answer, one way or the other. Some home pregnancy kits are not as accurate as others and you can obtain false negative results for a number of reasons.
You also need to ensure that you have been eating correctly over the past few weeks. If you have gained, or lost, a lot of weight recently then this can also affect your menstrual cycle.
Your best course of action is to discuss this with your doctor as he can give you professional medical advice.
