34 weeks tomorrow!

If I go into labor, the hospital won't stop it now. My doctor also said at the rate the twins are going with their weight will make it safe. But I had a lot of braxton hicks about 2 weeks ago but they stopped. I took a 3 hour walk with my son and mother today and I felt great. I have a feeling I might make it to the end of September, which is like about 3 weeks from now. My poor stomach, these stretch marks are going get worst.
