9 days late...

I am nine days late for my period, but still no positive tests. I have PCOS which makes my periods wildly irregular. However, OPKs have been very predictable for me. I got a positive opk on January 6th meaning I should have started on January 20th.

My husband and I have decided to really TTC this month but if I don’t have a period I obviously won’t ovulate or know when I ovulate.

So my question is how do I start my period? I know I can get provera from my doctor but she won’t prescribe for another week. Any other tips or tricks to become more regular?

Also, she’s suggesting I start clomid. Any experience with that medicine would be great!
