Do the benefits outweigh the risks???

This is my 5th pregnancy, 5th baby, and 5th high risk pregnancy. One thing that has never ever made any sense is why I go into preterm labor. I have always been healthy, always taken care of myself, never done drugs, and yet each time I go into labor early and for different reasons. It's honestly quite frustrating. I have heard people say "you are just so tiny, so you can't carry full term" (as much as I would LOVE to think I am that tiny, I have very dear friends that are tinier than me and have to get induced each pregnancy), "maybe my cervix is incompetent" (although this is a possibility I have gone through so many medical tests, and each time up until the minute I go into labor, every part of me checks out wonderfully)... I have myself thought up reasons why I go into labor early each time and why each time I go into labor more and more early. No matter what I research, it just doesn't make sense. I feel great until the day I go into labor. No major warning signs (I am so thankful that I journal cause I have gone through my history a few times), just BAM, labor, bed rest, bed rest works temporarily but ultimately I end up having the baby early, way too early. I was on bed rest for over a month with Trent, for a month with Macey, for almost a month with Maggie and only lasted 4 days on bed rest with Izzie. If I was in my 7th or 8th month before going into preterm labor it wouldn't be such a big deal, but 14 weeks before my due date is very scary, very scary...

So I am left asking myself again, "what is the point of bed rest and do the benefits outweigh the risks?"

Here are the benefits of bed rest:
     Bedrest helps to keep blood pressure low (for patients with these type of issues)
     Bedrest allows the body to stabilize itself and keep the weight and pressure off the obvious
     Bedrest decreases stress
Here are the risks of bed rest:
     Bedrest for long periods of time can cause a life threatening blood clot in your leg
     Bedrest for long periods of time can cause bed sores (gross!)
     Bedrest can cause your muscles to weaken along with your metabolism and endurance
     Bedrest can cause depression and feelings of isolation and insecurity

So, there you have it, those are the risks and benefits. Notice I did NOT include in the benefits a full term chunky monkey cause that has yet to happen for me :)

I am even more confused as to what is best, but for now, I am sticking with resting. I am only 27 weeks pregnant and have to make it through the next month. I guess I will roll over from my right side to my left side so I don't get any bed sores and make sure Craig reads these risks when he gets home and have him massage my legs, ha!
