Bleeding

So I got BFP on Friday..Saturday was bleeding heavy and cramping. Went to the EPU yesterday and HCG levels were 166 for 4 weeks. I have a history of misscarriages so they wanna keep an eye on me but I’d already told myself I had misscarried again! My bleeding had gone to spotting and has now stopped. I’ve done a pregnancy test again today before I go back tomorrow as I thought to myself I don’t wanna waste their time if I’m misscarrying and I got a more prominent line. Has anyone had anything similar?! They’ve told me my cervix is shut 🤷🏼‍♀️ first picture is from Friday! The second one is today? Could I really still be pregnant?! Ttc after misscarriages are just so full of worry😩
