It is possible that after this length of time you might be pregnant and if that is the case, you can always relay on doing pregnancy
test but i suggest you go to a clinic and get the test performed by a health expert either by dosing hCG
in blood or doing a urine test. But if the test is negative then it is possible that you are having irregular period and if this is your first time, you should not worry and know that most women in their reproductive age might experience irregular menses/ skipping periods.
Do take note that stress
, change of usual habits, food, abnormal hormonal
changes etc might cause this. So, just give it some time and allow your system to fix itself. It might come back in a few days, few weeks or months. The thing is allow sometime and avoid being stressed i.e if you are.
Wish you the best and hope this helps
