15 weeks, smallest flecks of blood after peeing.

Melissa
I saw the doctor about this already and they never called me back on if it was an infection or not, so when I wipe sometimes there are the smallest flecks of red on the tissue like you have to kinda squint to see them. And it's when I have to pee, so I don't believe they are coming from anywhere else. 
Also, I have been rather achy and unable to get comfortable when sleeping. Is this normal so soon?
