I have just found out am pregnant and I already have a DS. I am very early but have been suffering from severe nausea and I am not keeping anything down but dry toast. I am crying all the time and I am now thinking have I made a mistake trying for another child as I have DS who is 3yr and over the last week spent about 8 hrs in total out of bed. I am feeling useless and like a terrible parent and I dont think I can do it. I think if I maybe wasnt suffering with the nausea/sickness I would be better?
