I'm 16 weeks pregnant and I keep having this heavy/tight feeling in my uterus. Lasts for anywhere from 10 seconds to a few minutes. It's not painful but it feels very weird. No bleeding or anything like that. It does not happen regularly but at least 2-3 times a day. From what Dr. Google says it could be Braxton Hicks but this is awfully early is it not? I have a doc appt tomorrow so I will be asking her about it of course, but I was wondering if anyone had anything like this and what your doc said. Thanks in advance.
