Hi everyone, I've got a scan with the consultant in a couple of hours and i'm sooo scared and nervous. By my dates i should be 8 weeks today. I had a positive test and

did another one last week just to make sure i still was, not that it would tell me much, but i'm sure theres someone out there that no's why!!!!
So i've been telling myself that i'm not pregnant till its confirmed in this scan coz all sorts of things could have stopped it this early. I know i'm going to be upset if i've lost it. Doesn't help that my due date for the baby we lost at 20 weeks is next week. Some how i think it would help me feel better if i was pregnant. Is that selfish.
Anyway i'm really nervous and rambling on can you send me some positive thoughts and stuff please.
