Need some success stories!!

Okay ladies, I may be pregnant again after having 2 miscarriages. I'm so unbelievably scared. I would only be about 2 weeks (my last period was a little over 2 weeks ago) if I am pregnant, and I have a lot of symptoms like I've had before (slight nausea in the am, waking up at 530 am and not being able to go back to sleep, I'm very tired all the time, twinges of breast soreness randomly through the day, frequent urination, severe bloating). I took a test yesterday and it was pretty much negative (I think I see a very slight line, but my hubby doesn't see it lol). I'd love to hear some success stories of others who have had successful pregnancies after multiple miscarriages. I'm so worried that I will lose another chance at having a baby... I'm only 21 years old! I'm just worried somethings wrong with me & need some hope.
