Pregnant with no symptoms?

Jessica

I was a day late on my period last month and thought nothing of it. Had a short 3 day period and now I’m 4 days late on my period but I have no symptoms and I took a pregnancy test last month and two days ago and they were both negative. I called my doctor for a blood test because I’ve never just not had a period. Not on birth control at all either. Has anyone experienced this?
