First of all, it is very important to know exactly what you want. You need to tell your Doctor your worries and make her listen to you. Make sure she understands that you need answers. Secondly, do some research. Natural birth is called natural birth for a reason. It is NATURAL. Your body was made to give birth. If you can have this baby naturally, you should. I am 26 wks with my 2nd pregnancy and weigh more than I did with my first. I weigh 172 lbs. I have every intention of doing this natural. Unless my childs life is in danger, I will avoid a c-section. The state that I live in has laws about having a c-section with every birth after you have one. Make sure that isn't the case w/ you. You wouldn't want to have a c-section and learn that you can't give birth naturally now and regret your decision. Thirdly, you need to know about pain medication. You need to know at what times durring the pregnancy you can take them. If you are too far along it might be too late for some. Make sure you know. There is plenty of information online. I had an epidural w/ my first. It seemed scary, but was a life saver. I did just fine. It is different for every woman. Find out what you think you would like. Know everything you can about it. There are even videos that show how they are put in. Lastly, write out a detailed birth plan. Who will be in the room with you? What pain medication, if any, do you want? (Make sure you make notes of your medication and have a back up in case for some reason you can't have it.) Tell your husband or whomever will be with you exactly what you want. Make sure your nurses and Dr's know also. As long as you know what you want, everything will be fine. Knowledge is the best. I'm sure that you will do fine. Your body was made for this :)! Good luck!
