When will ovulation return?

Recently I went off the Xulane patch and my husband and I decided we want to have another baby. I am currently 314 lbs. i ave always been big. I have never had an issue getting pregnant. I have 2 health boys ages 9&2. But my family members are saying that due to my weight ovulation May not return is this true. This is my first time using the patch and going off of it. Has anyone got any insight?
