Symptoms goin in and out

I swear sometimes being in the first trimester and not yet going to your first appointment is so scary. I am approaching 8 weeks and my first doctors appointment isn’t until I’m 10 weeks and my symptoms come and go... I never vomited but I do experience nausea. Sometimes I don’t feel anything but just a heaviness or discomfort in my tummy and that’s what keeps me thinking I’m still pregnant. Don’t really like thinking bout that scary M word. Just thinking positive but my thing is just when you have little to no symptoms it kind of scares you especially if you haven’t seen your doctor yet😖
