Fertility problems after contraception

Amy
Hi ladies just wondering if any of you have had any problems with ovulation after coming off depo provera? The reason I am asking is that my dr doesn't think I am ovulating yet and may need to go on clomid to try help! It will be 2 years this year since coming off the depo and periods are horrendous, last upto 12 days and a full cycle can be as long as 45 days!!! 
I went on and read up a lot of people have this problem but doesn't seem to be as long. I have also read that raspberry leaf tea is ment to be good to help regulate and dong quai herbal tablets but would like advice to women who have tried/heard of them. 
Thank you kindly 😄😄
