Positive?

I had surgical management of miscarriage 3 weeks ago and they told me to do a pregnancy test. I did the clearblue digital which came up positive and called the EPAU. They told me to do non-digital ones. I always get evap and indent lines on the cheap ones so don’t trust them. Don’t know if the clearblue rapid is a positive or evap. Going out to get more tests and the EPAU phone line is closed now so I’ll take another one in the morning. Just scared I’ll need to have another surgery. Help!
