Nuvaring

Kristyn
Hi Everyone :)
I used Nuvaring after my first son, and when I stopped using it to try to get pregnant I gained 10 lbs. Regardless, I used it again after my second son, because I was comfortable with that method of BC. I just stopped using it one month ago to possibly try for our 3rd and final baby, and I'm scared to death I'm going to gain all this weight back again. I try to only weigh myself once a week, so I don't stress over it, but it's like I can feel my body getting larger! Does anyone have any experience with Nuvaring like this? 
Thank you!
