Question!

Em

Trying to figure out how far along I am before I have my 1st ultrasound Nov 21st. I had an extremely light episode of bleeding some red and brown blood starting september 23rd and lasting a few days. Not enough to wear a tampon or pad just noticeable when I wiped. My last full period was right around August 25th. I took a test on October 31st since my period had not shown yet. I had a blood test to confirm pregnancy as well. I'm kinda curious what you ladies think... any questions just ask! Thanks!
