Hello Anon
Thank you for writing.
If your pregnancy test is negative it's not likely you are pregnant but you can test again in a few days.

There are many reasons for a delayed period or a change in cycles that is not connected to pregnancy. Some of these may be a factor in your life, others may not but I will give you a run down of many reasons.

Stress
When you are under stress, your brain may go into alert mode, which can change your hormone levels, as well as affecting when you ovulate.
Ovulation is the time when your ovaries release a mature egg that is ready to be fertilized. If the egg is not fertilized, and does not implant in the wall of your uterus, your hormone levels change, and your uterus cleans itself out to get ready for a new cycle for the next month. That cleansing process is your period.
If you are stressed, you may ovulate later than normal, or not at all one month, which can delay or cancel your period for that month.

Hormone issues
Hormones are chemical messengers sent out by your brain to regulate many different functions in your body, including your period. Hormones need to be in proper balance for your body to function correctly.

Polycystic ovary syndrome is a condition that causes your body to produce too much of the male hormone androgen. PCOS can cause cysts to form on your ovaries, which can prevent ovulation and keep you from having your period on time, or at all.
Problems with your thyroid can cause the gland to release too much or too little thyroid hormone. Thyroid imbalance can also affect when you have your period. In this case, medicine to help your body have the right amount of thyroid hormone can get your periods back to normal.

Give yourself a few more days to see what happens and as I said, test again then if your period does not come along.
Best,
Susan
