Normal?

I am pretty sure this is normal but being the spaz I am need some words of encouragement saying it is...
​After going to the bathroom there was a light tint of brown on the toilet paper. Is this normal? I'm 5 weeks exactly. I just want to be sure it's not the start of something bad.
​Also, I've been cramping on and off since ovulation but nothing horrible (mild less the period cramps). Just want some reassurance. I'm a worry-wort.
