Spotting at 8 weeks!!!!!!!!!????????

Ok so maybe I'm panicking for No apparent reason...but at lunch today I went to the restroom and when I wiped there was the faintest pink, it was very watery and slippery. It now has happened every time that I use the bathroom for the past hour...its very light pink. My DH and I had sex last night, so I'm thinking maybe that contributed. This is my second pregnancy though and I did not spot at all with my first. I called the dr. and she said that 10-15% of pregnancies can spot in the first trimester and everything be absolutely fine. I'm not cramping or anything like that, it's just when I wipe. Has anyone else had this happen? I have a US scheduled for Tuesday which can't get here fast enough. I just now have to make it through the weekend. Thoughts ladies...and thanks!
