I think its fine I am 8 weeks pregnant with my 3rd child and I do a lot of reading, and it is normal to have light colored discharge as long as it doesn't turn red and clotting and cramping, I think you should be fine. I had a period with my first 2 for almost 4 months.....
I am a mother of 2 and expecting number 3 I dont know if this is your first but from my experiece that light disharge is fine light brown or pink, I think as long as your not cramping or having heavy bleeding or passing clots, I know our woman fluilds DO change...sorry so graphic, I do a lot of reading and they get thicker and all that good stuff......I know with my previous pregnancies, I had a period for almost 4 months, and my dr said it was fine.....good luck and dont worry....
oops I accidently sent two comments sorry....
