6 weeks and brown spotting

Hi ladies!

Should i worry that im having brown spotting when i wipe after peeing? Ive been having it for 3 days. Yesterday and today i saw there were little brown clots in the toilet after i peed. Im not cramping.

I know brown spotting is normal in some pregnancies but i need reassurance that all is fine. My first ultrasound is tomorrow and i cant wait to discuss this with my doctor.

Im trying not to stress about it but after an mc last march, i cant help but be paranoid.
