My story may help you a bit - so here it is to give you a bit of hope!!!!
I came off the pill in early june'06 after being on it for 12 1/2 years!!!!!
I got my first period 45 days later, my second one 50 days later and my third one 51 days later.
I went to the doctor and had a series of tests done, which all came back "normal". He said that sometimes your body can just take longer than usual to get back to normal and also that a healthy couple usually takes between 6 - 12 months to conceive!!! Sooooo, we tried and tried (for 6 months) and on the 7th "try" we got lucky and I found out I was pregnant on dec.27th!!!!
My preiods never did regulate before I got pregnant, sooooo hang in there and don't stress about the situation. I know alot of people here will tell you that, but it is so very true.
I wish you a ton of luck and am sending you lots of baby dust your way!!!!
