1500mg seems to be a fairly standard dose for PCOS. It may freak out some pharmacists as the usual dose for type 2 diabetes is only 1000mg. I'm not sure why the difference, but I do know that my first specialist only put me on 1000mg, and I got nowhere until I changed specialists and he upped it to 1500mg, and then the weight came off. Just be careful - sometimes it's better to go two weeks at one dose before you increase. Your side effects will be the best indicator of how you're going, though. Don't push it if you're not feeling well.

The most obvious sign that ovulation is going to occur is egg-white cervical mucus. It looks exactly like raw, clear egg white. It's very stretchy. If you're on clomid it may reduce cervical mucus, so you may want to be using something like OPKs, but I honestly found them to be more stress than they were worth.
