Couldn I still be pregnant

I posted yesterday very faint line I thought I may have had a chemical because I had faint test then some bleeding but it wasn’t like a normal period but it came the day I would expected it to come.. anyways after I’ve had some brown discharge but very watery so my doctor told me to take a test again I did yesterday afternoon and it was faint but didn’t know if it was an ident but there was colour (first picture) then I did one this morning FMU (second photo) it came up within 2 minutes and it looks darker my doctor has told me to wait to see it it come on my next period but that seems very far away...🙃 it pink in person very pink!! Should I take a digi?????
