Rainbow Baby BFP!!

Got my BFP this morning and we are expecting our rainbow baby 22nd September!! Excited and nervous...after suffering a silent miscarriage in September at 10weeks (baby stopped growing at 6+2) I'm feeling quite nervous about the next few weeks. 
Has anyone got any tips on how to get through the 1st Tri as calmly as possible? 
Also do you get offered any early scan when you've previously had an early silent miscarriage or do they just treat you as normal? 
Thanks for advise in advance x
