Hoping to get some answers this week!

Tomorrow I see my new OB and I am really hoping we can figure out what to do about my situation.  This past Wednesday I was in some pain like usual and when I got to work I had started spotting.  So I called my doctor and the midwife told me to go home and if the spotting got worse call and she was the on call for that night.  She asked about the pain and I let her know that I always have pain no matter what I am doing now even sitting but there are stages and different levels of how painful it gets.  If I am not doing much or start to get more pain and I am able to stop what I am doing and put my feet up and stay that way it won't get worse.  If I can do that it just goes from bad to worse.  She tells me its probably just round ligament pain.  I am know what that feels like and its not it!!!!!! Also round ligament pain doesn't last all the time it goes away and mainly happens when you are changing positions.  So that just really made me angry!!  I have already had issues with the midwives in this practice and this was the icing on the cake.  By 9pm Wednesday night I was in so much pain and had a hard time walking.  The pain then moved to my back so I just went to bed because I didn't want to call her again because I knew she would make me even more angry!
Every day at work I leave in pain.  Alot of the time I work longer than the 4 hours I am suppose to work and all the up and down really contributes to the pain.  I know its hard for work to accommodate the 4 hour shift because you never know how many customers will be in the store and how long each transaction takes.  I know my managers are frustrated at the schedule and  I am very frustrated with all of this but my main priority is not work its making sure I carry these babies as long as possible and hopefully not killing myself trying.  I really hope my new OB can help me and maybe figure out what is going on!  I am hoping if we can figure out what is causing the pain we might be able to avoid it.  I also want to be able to control what I do.  If I start to feel more pain I would like to be able to stop what I am doing and rest because I feel that its my body telling me to rest and slow down.
I knew that a twin pregnancy was high risk and there are more complications that go along with it but I didn't expect what has been happening and I hate feeling so useless.  I hate not being able to get things done.  However everyday I am just so thankful I am still carrying 2 healthy babies and this is a small time in my life and when I am holding them in my arms it will all be worth it!
