a little bit worried

Rosangel • Already have a boy that is 6 year`s old and a girl 2 year and almost 8 months and pregnant with my third baby 😍😍😍
Today I am 6 weeks 6 day pregnant and when I wake up to pee and I dry my self I saw a little bit oh pink on the paper but it was only at that time after that I had go the bathroom like 15 time already and the paper is clear should I be worried?? I was thinking on going to the emergency room but I call a midwife that is my friend and she say that if is not red blood and lot I should not worried that sometimes that happen when the body is assimilating the pregnancy better or when the progesterone level goes up ... did any other expecting mommy went though this? 
And all my síntoms are the same frequent urination a little bit of nausea cravings pain in the boobs please if some one else had gone trough this live me a comments thank you for taking your time to write and read  me blessed to everyone
