Hello everyone! 33 weeks, and I feel like I'm about to give birth tomorrow. The last three days I've been feeling incredibly tired, I can barely get up, my body is heavy, although I've lost 5kg during pregnancy, I haven't gained anything back. What can I do to help myself? Also, tell me, has anyone experienced restless legs syndrome? What did they do? I'm itching all the time, it feels like constantly, everywhere. Today I only noticed. And who knows about calcium oxalate crystals in urine? Is this definitely kidney stones? I've never had such a thing, I test my urine every two weeks. I'll see the urologist
