After reading some of your questions you've posted on here, I also agree with kristina. It is very important you go and see your gp now, they will be able to answer any questions you may have, tell you what you can/cant do, can/cant eat etc etc and a midwife will then be able to oversee your care during your pregnancy.
It doesnt matter what age you are, (I was 19 when I had my ds) it is important that you are receiving the proper care.
