When I lay on the floor on my stomach, my uterus feels like a hard lump. It’s like the feeling is very apparent and I don’t remember feeling my uterus as a hard lump when lying down on my stomach in the past, it’s kind of uncomfortable to lay on my stomach because of it. The only time I can recall having this feeling before is during pregnancy. But I just recently took a test just to make sure I wasn’t pregnant. Is it normal to feel this hard lump of a uterus and I just haven’t noticed it before? 🤔 *anxiety kicking in*
