Need Advice Pls

I have had a really easy time of this so far.  Tonight, however, I have started lightly spotting.  I didn't have incredibly high prog numbers initially (11.7), so I wonder if it is that.  We are supposed to leave for a family weekend away on Friday to an amusement park all day Sat and most of the day Sun.  I wasn't planning on riding much of anything, but we are taking DS (14 and 11) for an end of the summer trip. 

Here is my question...even if the bleeding stops, would you still go on the trip?  I feel like I am asking for more bleeding being on my feet that long two days in a row.  Of course, the trip was planned pre-BFP.  TIA.
