Worried

Kayla • 27 year old social worker who can`t wait to have a family of her own!
So I finally got my BFP after having a miscarriage last month. 
I went to the bathroom today and have some pink colouring on the tissue paper, I see that and I instantly start to worry. 
I worry about me doing something wrong. I don't have any cramping but I have been quite sick the last couple days! 
Have any of you ladies had this?! I hear it's normal but with someone who has has 3 miscarriages is very hard to not freak! 
Any advice would be appreciated :) 
Thanks for reading ladies!!
