randomly shivers in my tummy. I dont know how to explain it. It has happened probably 4-5 times in the last couple of weeks, 3-4 times each time. The shivers arent long, and the 3-4 times are probably done within 30 seconds. But my tummy actually like shakes. I am 36 weeks 2 days today. Any clue what it actually could be? Since babies arent spost to be able to get cold in the womb? Im not really nervous about it, just more curious.
