Bfp and concerned...

So I did get my bfp at 12 dpo. Yaaaay so thrilled and excited! But I also miscarried unfortunately back in September. And had some spotting which I know can be normal and cramping also. My question is to the moms who have miscarried before and are pregnant again, how did you cope with being constantly nervous and scared that ever little pain is something bad happening? Trying so hard to stay positive. How did you?
