Hello everyone! The 39th week is going on. The second day I feel nauseous, it's not throwing up but I feel nauseous. Weakness, slightly sore but without temperature. Anyone know what this is? Is it related to pregnancy or did I just get sick? ??‍♀️ I don't want to feel like a rag doll for the rest of my time until the birth.
