How did your weight affect your chance of getting pregnant?

Zheyan • I`ve been married for a year and trying to get pregnant. Never used birth control pills hoping to be pregnant soon!
My weight has gone from 130 to 160 in the last three years!! I am only 5ft tall and have a sitting office job that makes it super hard to loose weight! I am curious if your weight has a major impact on getting pregnant?  I have been trying for 10 month and so far I am not pregnant, my cycles have been messing up whole lot?
