Jude, I had a look at beta base in the age group from 42-45, the fastest doubling time in that beta range was 21.16 medium was 39.58 and slowest was 140.75 that was 90 women reporting and they all are supposedly pregnancies that showed a HB. I think keep hopefull and try hard not to worry especially when you still have strong symptoms. If it goes backwards, worry then. Hugs and best wishes, I hope it works out well.
