Due Date Mess!!! 😩

Okay you guys so I'm not all that happy with my doctor and medical care, but I'm getting medical care at a military base and there is basically nothing I can do to fix the problems I'm having with them. The biggest and latest one is for a few months I kept asking my doctor to look into the accuracy of my due date because I felt like I was a good bit further along than they told me. After a lot of reading about symptoms and what should be going on each week and noticing that for me all those symptoms had already passed I was also carrying very very heavy and was even told by several mothers that I worked with that there was so way I wasn't further along. I was just way too big. So last week my doctor did not make it to the appointment and they had me meet with a midwife instead. When the midwife measured my uterus she said I was measuring to be 38 weeks along not 34. I had also gained a whopping 4 pounds in 2 weeks which was strange because I was on my feet a lot (2jobs) and I have a fairly balanced diet. I should not be gaining 2 pounds a week at 34 weeks. She set me up with a growth scan for a little over a week later (this Friday), but according to the midwife I could go into labor any day! So long story short I want you guy's opinion! I'll post a picture of what my belly looked like (supposedly at 34 weeks) and let me know what you think. I'm kinda freaking out because I might have just lost a month to prepare and every little pain I feel I get on edge about starting contractions.
