Not ovulating or late O

Kim

So long story short I have PCOS and this is my 1st month on clomid I took 100mg on cycle days 3-7. My RE had me come in for a U/S on cycle day 16 because I had not had a LH surge yet. My egg sacks were only 8mm so they said I was not going to ovulate. My doctor wants to up my dose to 150 next cycle. I'm currently on cycle day 21 and still have not had a surge so I'm guessing I'm not going to. Has anyone had this happen before? Did you end up ovulating?
