Did you conceive after weight loss or changing eating habits ?

Hi all! I’ve been trying to look for forums about women conceiving after losing weight but can’t seem to find any. So my questions is , have any of you struggled with infertility and decided to lose weight and got pregnant ? I’ve heard being over weight can cause infertility. I am over weight and want to change my diet but I’m hoping it will also help me get pregnant please let me know. Thank you!
