Anyone else have recurring spotting?

Mama Of Klara👶🏼 • Taken since 06-24-2010👫💍 3 angels 👼🏼👼🏼👼🏼 🌈 Baby due October 2018

First time was at 10 weeks just light brown. Second time was at 11 weeks and it was one small blob of red, now I’m 12 Weeks 2 days and it’s a mix of red and brown. Light only when I wipe but it’s still there and it scares me :( saw baby at 10 weeks and heard HB at 11 weeks. I just get so scared :( I have light cramps this time!
