Prego after 2 mc. scared :(

Bridget

Well i found out i'm about 5 weeks pregnant. I want to be excited, but I'm scared. I've had 2 mc one was 3 months ago. I've been having spotting with this one since the beginning... everyday for over 3 weeks now. it actually started 4 days after my last period. it's brown, or a light pinkish brown. maybe 5 times it seemed there maybe was a tiny stringy small piece of tissue? doctors say this is normal....old blood from implantation, lots of other reasons, etc.. no reason for concern. blood work today confirms pregnancy about 5 weeks.. this means I somehow got pregnant day after my period ended.. a blessing, so trying to trust this is meant to be thus time. But i didn't experience this spotting with last pregnancy. I miscarried around 5-6 weeks so about this far along for the last one. it's making me incredibly nervous. how can you be excited? has anyone else experience this is pregnancy and gone on to have a healthy pregnancy? I'm trying not to let fear overcome me.. negative persists far more than positive, it's just so hard.
