Early pregnancy symptoms

Kisses

So today I'm 8-9 dpo. Yesterday I threw up my lunch and felt better most of the day until bedtime. I felt whipped and nauseated !. My lower back has been hurting on and off with mild cramps that are felt on one side and then the other. Woke up this morning really tired and major dry mouth. What do you ladies think. I'll probably take a test Monday or Tuesday. Trying not to test too soon !
