Weird symptoms

Anon

11/15/22 - My period is a day late. I'm having lower abdominal cramps like my period though. My lower back on the left side hurts (same side as my cramps). I'm also having some mostly white, but slightly pale yellow creamy discharge.

11/15/22 - Update! Negative test, but still no period. Discharge is still very creamy and slightly pale yellow.

11/17/22 - Update #2! Now I'm 3 days late.

11/17/22 - Update #3! I had unprotected sex Oct. 24th and took Plan B Oct. 25th, could this be the reason for these symptoms?

11/17/22 - Update #4! I started barely spotting at night. Like, a few drops of pinkish spotting, that only lasted for a few hours.

11/18/22 - Update #5! Still no period, no spotting at all today, and a negative pregnancy test.
