weight gain with enlarged uterus

Hey girl. Of course it is because large uterus has many symptoms, and swelling and many more are one of them. So, you shouldn't be worried about that. But, I have a question for you? Have you been to your gynecologist recently? If not, I strongly suggest you to go and find out what's going on, why is your uterus enlarged. Most common reason for that is fibroids, and they are benign so you shouldn't be worried about that, but there might be something more. Go to your gynecologist, he will tell you what to do next, or prescribe you something.
