My husband and I just had our 17 week appointment, and heard the heartbeat. I'm not sure what my pre pregnancy weight was, but at 10 weeks I weighed in at 289lbs. I'm 5'9 & my weight is pretty much in my hips. The dr told me she only wants me to gain between 11-20lbs my whole pregnancy. I am starting to lose weigh. At my 17 week appointment I weighed 282. They haven't complained... yet. Hopefully it doesn't harmed the baby. FTM.
