So, I am somewhere between 7 weeks to 8 1/2 weeks. Sonogram shows closer to 7.  I am posting because I am driving myself a bit nuts. I have been spotting light brown on and off since Thursday evening (about 4 days now). No cramping. The spotting mostly only shows up when I wipe after urination. On a couple of occasions, it has left a small mark on my underwear.  Should I be worried. This is my first pregnancy. My mom never had any spotting. When should I call my doctor? When should I worry? Any advice would be awesome. Thank you!
