Dear kjw
Having a late period dose not necessarily mean you are pregnant. There are plenty of other reasons for a missed period. For example poor eating habits, hormonal changes, and sometimes people just have irregular cycles.
On the other hand a negative test dose not necessarily mean you arn’t pregnant. It could just be that it’s to early to tell. Also some women produce lower levels of the pregnancy hormone.
I suggest that you go to your local clinic and ask them to do a blood test. Blood tests can detect pregnancy sooner and are more accurate.
Best of luck to you!
