scared!! opinions please!

I am 7 weeks and 1 day today. I saw my baby's heart beat at 119 on Thursday. I am some what of a high risk pregnancy because I had an ectopic in February . This morning I woke up to go to the bathroom and when I wiped, it was pink!!!!!! Should I be concerned? I have not had any bleeding or spotting at all, ever during this pregnancy. I feel a little crampy but I don't know if that's my mind playing tricks on me. Does anyone think I should go to the doctor? Is this normal? Yes I know I probably sound paranoid but I really don't want anything bad to happen. Please let me know.
