Confused

Hey everyone this is my first post ever. I’m so nervous lol.

So my period was last month on the second. The one for this month is supposed to be on The 23. I been feeling off . I went to the doctor and received a big fat negative. The 23 is in 1 day and still there’s no sign of a period. TMI ((sorry)) all I been getting is creamy white discharge.

Any advice?
