Im hoping someone can help!! Please!!!!

I found out i am around 5 weeks pregnant and i still havent had my beta work which i originally had on tuesday but now im changing it to monday. Since yesturday i had been having this super light light pink tinge but only when i wipe. Does not go on my undies. Just when i wipe and its hardly there but it is there. Is this normal? Should i go see my doctor? Ive had two missed miscarriages before and i really dont to loose this pregnancy as well. Should i be worried? Please anything helps!
