Early Miscarriage confirmed. But, No heavy bleeding?

At Very early 5.5 weeks I got confirmed from doctor that I am miscarrying. Of course it has been a very rough week, but I am coming to terms with it. Most frustrating is that I haven’t had the normal symptoms and also my body is confusing me. Lines on tests started getting fainter, and my preggo symptoms went away. I had very MILD cramps for 3 days (usually have intense period cramps) and some brown spotting - never red. Never alarming. My hubby and I BD and there was some extra fluid after (which was weird), but it wasn’t blood or colored just watery. 2 times when I wiped there was a brown snotty mucus substance - that’s the most “alarming” of signs but it still was just a little and didn’t seem crazy. Then, I got blood tests done & a 48 hour test, HCG levels went from 12 to 6 in 2 days...so extremely extremely low. I have no cramps. Just very very mild light brown spotting a bit.

Anyone experienced a miscarriage and not had crazy blood and cramps? I’m not sure if it will happen in the weeks to come or if it already did and was just not the “norm” of heavy bleeding?

Looking for anyone who has had a similar experience! 6HCG is so low that it seems my body should be getting the signs.

Of course, just want to move on and forward so we can keep trying 💕

Thanks in advance to all!
