I have got an ultrasound tomorrow. I am nine weeks exactly tomorrow and i am so worried that there wont be a heartbeat or some thing else will have gone wrong. This is my fourth pregnancy. 2 miscarriages and 1 chemical. Please tell me i am worrying for nothing. I want this baby so badly. My first pregnancy i found out at 12 weeks there was no baby. Just a sack. I know it is unlikely to happen twice but i cannot help but be terrified. I am so tired but doubt i will be able to sleep tonight.
