Symptoms went away


So I was actually happy to get some pregnancy symptoms a few days ago. Basically I felt hungover. Headache, nausea, fatigue. I felt this for about 3 days including yesterday morning but then my symptoms went away around mid-day yesterday. Should I be worried that the symptoms seem to have disappeared? No bleeding. I get my blood checked tomorrow and then again Friday (this had previously been planned by my doctor to give me peace of mind that my levels are increasing). What do you think?
