I am 42 days pregnant today and I am 32 years old. This is my 3rd conception after 2 missed miscarriages. What worries me a lot is that I've had brown spotting 2 days back. I haven't had any cramps or spotting since then but today I saw dark brown blood when I wiped. Is this of serious concern? I have my 1st ultrasound scheduled on March 30.
