Sorry to hear about your chemical pregnacy

.
It is possible to have PCOS without your bloods showing that you're likely to, though - just something to bear in mind. FA will probably do a scan at the appointment, though, so they'll be able to see for sure if it's a problem. Is your period regular?
In any case, because you asked - you will be OK. Infertility is a long and hard journey (I'm sure the seven months you've been though already have been bad enough). Regardless of what news you get at your FA appointment, you'll find the strength you need, and the chances are very very high that in the end you will get there. All the best for the trip to that point, though, it can be very hard. The ladies in the infertility section can be a huge support, if you haven't popped in there yet?
