Feeling unsure tmi

Chrissie
This has happened like 4-5 times so far throughout my pregnancy.  I'm currently 24w5d and just had my monthly checkup and ultrasound yesterday.  Everything went really well he weighs 1lb 10oz and all of his measurements and scans came back great.  My placenta is really high too so the devote isn't worried.  The reason I'm feeling uneasy is sometimes when I go to the bathroom and make a bowel movement I spot light peachy pink from the front and its def the Front turns to brown and goes away very very small nothing even on underwear.  I have a cold and tonight I was blowing my nose when I was peeing and it happened again.  Every time I tell the doctor she is not concerned and we just saw him yesterday and I feel him move still tonight.  Has this happened to anyone else or anything
