Irregular periods

Ashley
Okay ladies I'm in need of some help... my periods usually come about every 33 days which I guess is my normal but last month I was on cycle day 54 before I started and this month I was cycle day 38... we've been trying for months now and I'm feeling a little disscuraged in the who process.. so my question is there any vitamin or supplement I can take that will help regulate me and help me ovulate?? I'm desprate.
