Positive frer then negative...frustrated

Michelle

So I got a positive frer on the day my period was due (last Tuesday) but on Thursday I got a negative digi and Friday morning negative test at midwifes....I’m still not bleeding which would make me 6 days late....I don’t get it did I have a CP and bleeding not started or could I still be pregnant? Been trying for 2 years I just pray this is it 🤞
