I need opinions

So it’s been 3 days since my very faint positive pregnancy test. I took 2 and they were both the same. I went ahead and took another one today and it was negative.... I don’t know what to do, having told my husband and best friend that I’m pregnant. I emailed my doctor about the faint lines, to see when it’d be necessary to go get a urine sample and blood test done, just waiting on a response now... I just don’t know what to do now. I need all the positive vibes and opinions I can get.
