Please help mc

I was bleeding exactly 2 weeks ago, I then did a test (numerous) which were positive, i then started spotting again and went to epu yesterday where they did a scan and bloods, they saw something the scan but werent sure if it was a cyst or start of something, they've called today and said my hcg is 154 but progesterone is 2 which is really bad i know, what im struggling to get my head around is my tests are getting darker, anyone been through this? Bottom one is a couple of days ago, thanks
