Strange spotting

Dlather

im 14 weeks tomorrow and a week ago today i had "spotting" that lasted maybe a half hour..definitely wasn't long anyways and only appeared when i wiped myself. Called the dr and they didnt seem too concerned..it wasn't red more brownish and didnt really have any cramps.. 

Today i have the same thing happen same thing happen only this time its bright red and i bled enough to change the colour in the toilet...oddly i stopped bleeding after i finished wiping myself...again no cramps but im so confused..anyone experience something similar? the only things ive read involve the girls actually bleeding for a day or two and i really am not full out bleeding..ive worn a pad each time to monitor the situation but its only appeared when i wipe myself..

i see my doc in two days but want a little more peace of mind..
