Please help, I am worrying.

Hi, I am 22 and I have been off the pill for around 2 years. I have been to the doctors regarding my periods as I have been on since 23rd Dec and I am still on now! However, my previous period was in August. The doctor checked my bloods and advised me that my hormone levels are normal apart from my LH levels which are very high. I have to go back for an ultrasound to check for PCOS. Has anyone experienced any of the above and is able to tell me their experiences?
I am very concerned about ttc as everything I have read points to infertility. Is it possible to conceive with high LH levels? Any help or comments would be greatly appreciated as this is all I can think about. X
