Hope friday brings some answers honey.....when we had our chemical my levels started off at 40ish at 14dpo (had been getting BFPs since 12dpo), 2 days later they hadn't risen but I had started bleeding, they then left me for a week telling me there was a 5% chance of ectopic (as levels hadn't risen but hadn't dropped) but probably it was a straightforward miscarriage. after that week of total stress they got me to do a HPT which was negative and that was the end of it.
If you get any strong pain take yourself to hospital asap as if it is ectopic there is a small chance it could rupture and cause a lot of problems, although I was told that this is quite unlikely so early on.
Really hope its good news for you
