I think its natual to worry when you have gone through so much. with my family history and me being so sick I still worry i will lose my baby. But dont worry - the baby is getting stronger and stronger each day - take one day at a time and enjoy what is happening. There is no point saying not to worry because you will, so give yourself 5-10 mins a day to worry and then dont for the rest of the day and dont forget if you have any concerns check with your Dr or go to the hospital they are always happy to help or answer any questions. Congrat and good luck
