Damn pregnancy anxiety....

8 weeks tomorrow and have been spotting the last week. Menstral like cramps and color ranging from red, brown, pink, I had to put a liner on after I stained this pair of underwear. I know it's normal for early pregnancy but anxiety is through the roof. Just had a Dr's appointment yesterday and I told her I'd been spotting but I'm slowly getting more and more of it. Ugh, Thursdays ultrasound can't come fast enough.
