I need someone to vent too.. long post but would appreciate feedback 🥺

Ladies I’m beyond emotional.. (a little back story ) my cycles are extremely irregular due to my PCOS, so I started a weight loss journey to get my weight down to help me conceive. I am down 25 lbs with the help of keto and my period came back within the first month of dieting. However, period never came this month. I am not pregnant and I’m still not ovulating. I test opk twice a day because I have never gotten a positive and not sure if I even ovulate. I have been pregnant before, but I was about 65 lbs lighter. Should I seek fertility treatment? I know it’s expensive but idk what to do... I’m so frustrated and feel like giving up dieting nothing is helping...

Baby dust to all you ladies 👶🏻 💫
