Thanks for using Doctor Spring for posting your query.
I have gone through your question in detail and I can understand what you are going through.
Delay in periods is common and 1 day missing of period is not an issue. Further there is no specific sign of pregnancy. If you have a doubt, you may get a urine pregnancy test done. That's the most specific test to confirm the diagnosis.
Hope this helps,
In case if you have any further query, do let me know.
