2 positive results 1 negative

Hi my last period was 5th jan, so i'm 4 weeks and 3 days gone, i tokk 2 pregnancy test, both came back positive. (even asked my partner to check, just incase my eyes were playing tricks on me, which even he confirmed that there were 2 lines, very faint). Started seeing a little bit of blood was ligt pink now brown, sorry for the detail, so took another 1 tonight but that 1 came back negative. I have no pain, but still feeling really tired and sick. Can anyone give me some advice please. Wrried sick and so scared. Can't have a early scan because i'm 2 early
