Confused

Okay ladies got a question..... I know I post atleast once a month it seems like it but my husband n I have been ttc for 3yrs and 1 month, we believe my ovulation was this past Mon but here is the thing starting last Thursday I felt nauseous went on for several days(thought it was because of the funeral we had) n hungry all the time (again several days), had all sort of salted items yesterday then was okay. Now this morning cramps n and a okay stomach.

Mind you the cramps were light cramps n a light nauseous pain in the stomach plus yesterday I had 1 dot of pink when I wiped n nothing else... What's going on here? Help please?
