Feeling down today and looking for a success story

Me and my partner have been trying for nearly a year and half now, when I had blood test done everything came back normal other than I don’t ovulate every month which they’ve put down to weight but does losing weight really help with ttc 🤔 sorry for the long post but a family member just announced their pregnancy and she’s a lot bigger than me so it’s made me want to give up 🥴
