Losing the war- IDK whats happening please help

July of last year I had my Mirena Coil removed and we were so excited to try for a baby. My husband and I have our own children but none together. I will be 35 this year and I have teenagers. So Jan rolls around and I am positive I am pregnant as I missed two whole cycles. Tests are negative, I go to the Dr and its to find I have a hydrosphinx in my left tube. I have surgery for the partial removal of my tube and on 3-10 get a positive pregnancy test. I will add I wasn't even late for my period yet but I was charting,had an old test laying around n just peed on it. I was so excited and surprised for that positive!
My husband and I went on vacation this past weekend and on Sunday I woke up to brown spotting. There was no hospital to go to, but we looked it up and kept seeing it was normal - implantation bleeding it said as my period should have arrived just the day before. Scared we leave and come home early. The bleeding continued, but it is only when i use the restroom its a brown and dark color and sometimes looks gritty?. I am wearing a light pad and its always clean. I go in to the emergency room and they do an ultrasound trans vaginally. The technician said there was nothing there and my HCG count was only at 40.
I followed up with my dr for another count to see what happens,no results back yet, but they are telling me basically that I have miscarried.
I had one ten years ago and it was simply nothing like this. I have no cramps, no pain, there are no clots, my breasts are still tender, I am constantly nauseous, although that may be from the stress.
I am confused and angry. I feel as if this simply wasn;t meant to happen because of everything I have been through trying.I feel like its my body so I should know whats happening and I don't. Should there be next to no bleeding if I was that early? With an HCG of 40 surely it was very early on. My husband is upset and we aren't really talking about it to each other. I can't talk to my friends because saying it hurts so bad I am a total wreck and have no clue as to whats going on with my body. Thank you for listening.

What you have described does sound odd as even if you had had a very early MC I would still expect you to bleed more than you describe. And it doesn't sound like you've had an AF either.

I think you should speak with your GP again once you have had the results back.
