Faint line! Please help!

Hi guys!

I took a test one day after my missed period and got a very faint pink line. I took a clear blue test 5 days late and still a very faint line! Both were checked with in the time frame so I don’t think it’s an evap line. I’ve never missed a period before. I’ve been super gassy, and bad heartburn. I have an appt next Tuesday but I’m so nervous that I’m just seeing things!! Please help! I tried to take good pics! I’m freaking out over here!
