40% rise in HCG (slow rising)

I’m trying to stay positive because I do have a gut feeling that everything is ok but,

I’ve been in and out of the EPU all week for scans and bloods after a bleed. Nothing on the scan and HCG was 402 - they thought I’d miscarried or I was a bit earlier than expected.

48hrs later HCG was 562 - 40% rise. So no miscarriage but now we’re trying to rule out ectopic.

I’ve no signs of ectopic aside from that bleed and light brown discharge in the days after it.

I’ve read some old threads but those slow rises were much slower than mine.

Anyone have anything they can tell me in terms of what to expect?
