Spotting

So I'm a little nervious I'm 6 weeks pregnant and I woke up this morning to brown spotting when I used the bathroom. I wiped twice and then it went away. No cramping. I already had spotting when I was 4 weeks which was little pink and then turned to brown. That went away after 2 days, it was on and off. This is my second pregnancy (rainbow baby). With my first pregnancy I did not experience this. I called my high risk OB and she just won't see me. What should I do? I'm trying to stay positive.

update: So this morning I woke up this time with pink spotting and a little bit if red. It stayed for about 5 to 10 mins and has gone away. I also had some light cramping. And niw my vagina is sore in a way. I'm going to head to the ER today. TMI PHOTO, TMI, TMI, TMI!!! ..........................................
