Contractions or not?

Hi girls, I am a little puzzled since yesterday. I read some articles on Braxton hicks contractions since my doctor kept asking if I have any since week 16, I am 27 weeks pregnant now, and I was extremely bloated the last 2 days so I though that might be contractions. I went in to see her in the morning yesterday and she claimed that I was having contractions when standing up, but then when I lye down the belly was super soft. Guys my belly is quite big and bloated since I got pregnant and kind of sticks out, but I don’t feel and discomfort or tightness. I went to see an other specialist the same day, just a few hours after since my “diagnose” was based on just the feel of my bum and no medical exam and she put me on bed rest for a month and threatened to leave me in hospital if I don’t keep the bed rest. The second lady doctor made a full check up the the cervix, placenta, baby’s heart beat, by blood pressure and guess what- I was perfectly healthy and so was my baby. My cervix is 5centimetres long, no shortening at all which I think is great! My question is has this happened to any of you- firm belly when you are standing up and soft when you lye down and I am puzzled on why the first doctor though immediately it was contractions without any check up?
