Girls, 35 weeks of pregnancy. I can't help but feel like I'm about to give birth. I've also become incredibly irritable, my cervix has receded, and I have terrible trouble sleeping at night. And it's very difficult to walk because my lower abdomen is putting a lot of pressure on me, from which pain started in the ovaries. Now I woke up and it seems like I breathe easier. They all say that I'm overthinking and not giving birth earlier. Do you think I'm overthinking or are my feelings real?
