So confused! Please help.

Ok so last Thursday I got 2 BFP after trying to conceive our 2nd child. On Sunday I started bleeding, quite heavy fresh blood. I went to A&E and she tested me again and I was still positive. She said to go back the next day so I did and saw a different doctor who tested and said it was negative and I had miscarried again. My world fell apart as you can imagine. Anyway this morning I went to my GP for a sick note and they asked me to do a pregnancy test before cancelling my midwife appointment so I did and it was a faint positive??? As you can imagine I am all over the place with emotions. I’m just so confused, I was 5+2 weeks this time but last time I was 6+6 and that was SO HORRIFIC, physically. I lost so much blood and clotting and had to be hospitalised and have a d&c where as this one has been nothing like?! I’m so confused. Have I miscarried or have I just had a bad bleed during early pregnancy?

Please can someone shed light? I feel so alone and so confused xxxx
