Pregnant after miscarriage

I just found a few days ago I am pregnant again .. I am over the moon .. has been 11 months since my first pregnancy that ended up in a miscarriage at almost 7w ... We have been trying on an off since then and it finally happened!

Somehow this is just a bittersweet feeling We are over the moon for finally having this miracle happening but at the same time I can't help but worrying because of what happened with the first pregnancy ... I have scan in 2 weeks just to make sure everything is fine and then another one at 8w for the heartbeat! I don't want to get head over heels because I am sooooo afraid I can lose this pregnancy too...

How did you manage to enjoy your second pregnancy without worrying ? I really need some good advise ladies !!
