Am I worrying too much?(KINDA LONG)

Is it bad that I feel the need to hear/ see my son breathing when he's asleep?
He's is now two weeks old and since we've been home he's either slept in bed with me or in his swing, which I had right by my bed because I'm terrified of SIDS. (I know I'm not supposed to do ether one, but I'm scared) I know they say no loose blankets, no tummy sleeping, nothing else in the crib but the baby… but my niece died a year and a half ago at only 3 months old..and my sister followed those rules to a tee…I have a crib but until about an hour ago it was on the other side of my room (now it's right next to my side of the bed.)
