Wa'alaikumassalam sis, I'm so sorry you've been through this twice, that must be heartbreaking, especially after waiting 7 years. Please do see a doctor or specialist soon, okay? Recurrent miscarriages ada many possible causes, and PCOS is just one of them, only proper testing boleh tell you what's going on with your body. Jangan main-main dengan ni, kena check hormone levels, clotting factors, and scan to make sure everything's okay. A few of us mums in my circle went through similar, and each one had different reasons, some thyroid, some immune, some even just bad timing. The important thing is you don't blame yourself; it's not your fault. Many get pregnant successfully after this, tapi kena find out the actual cause first. Take care of yourself emotionally too, this kind of stress is real. Talk to your partner, your doctor, or even a counselor if you need to. You're stronger than you think.
