I don't wanna call and bug my dr so im wondering if you ladys know what's causing this pinching feeling in my uterus it just happens every once in a while and it's not unbearable just kinda uncomfortable im 10 weeks and 2 days it's started right at 10 weeks . It probably happens like 4 times a day . I looked it up and it said its probably from my uterus growing but I'm just wondering if it could be something else
