Catyo, you could still have a tiny trace of the pregnyl left (ie a squinter) if your test is very sensitive, but at 15dpo you should get a clear line (not always dark, but a definite line instead of a shadow) on most tests if you're pg, so you should be able to tell if it's a real BFP (clear line) or leftover pregnyl (squinter).
Beau, I'd say that's fine. I used to do the same when I was working full-time. I got home a bit earlier than you but also did the morning one a little earlier.
Jasmine, yay for the witch finally leaving! GL with your lining!
Afm, doing fine. For some reason my FS has decided his patients have to split their FSH doses between morning and night, even at lower doses, so I'm doing an extra shot each day (which, as a recovering needle-phobe, I just love...not). AF stayed light and ended a day early so I have a slight worry that I'll get to Saturday's monitoring appt and be told it didn't shed properly and has therefore not re-grown properly, but I'm hoping I'm just over-thinking it... It's normally very thick by the monitoring appt (eg 13.5mm last cycle), so will be interesting to see what it is this time...
