Brown mucus discharge

Hi i am 7 weeks and 2 days pregnant. i have been having some tan colour discharge on and off. Last night as i wiped there was some brown mucusy sticky discharge on the tp again this morning when i wiped. I am so worried im not having any pain jus a few mild cramps here and there but have had these throughout pregnancy. When i was 5.5 weeks i had brown spotting and the doctor said it was implantation bleeding when the placenta is forming however im 7 weeks and 2 days now and its more mucusy and a lot more. HELP
