TTC - Missed Period - Symptoms

My period is 5 days late. I’ve been having fatigue and diarrhea. Last week I had a bad migraine, cramping, and threw up. Today is Thursday but on this past Saturday I took a test and it was negative... I wanted to wait a little longer instead of getting my hopes up and wasting tests everyday.

Did anyone experience any of these symptoms before finding out they were pregnant? I’ve heard of constipation but wasn’t sure about diarrhea?

Praying it’s a baby!
