sorry to read about your recent 'bubble'.

for my d&c last year, af returned just over 6 weeks later. sometimes it can just take a bit longer for things to get back on track.
also, last year i had a cycle that was up to 46 days so my FS prescribed a medication to bring it on (i think it was provera... something starting with 'p' anyway...). took it for 5-6 days, then stopped - af arrived a few days after that. you could ask your OB/FS for something similar if you would like af to get here sooner rather than later.

hope your af sorts itself out soon.
