Hmm I wonder

So my last period was right before thanksgiving. It is now Christmas and it still hasn't arrived. (You do the math lol) I took two pregnancy tests Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and the both were positive (yay me right?). When I arrived at my folk's place this evening I noticed a little reddish-brown spotting when I used the bathroom. I'm a little worried. Is this normal?
