Bleeding 4weeks and 2 days pregnant...normal?

I've been experiencing light cramping for the past few weeks and extremely light spotting (brownish) maybe 5 times. Last night when I wiped in the restroom there was dark red and brown blood. No bllod on underwear or pad, but when I wiped it seems like a lot. Few small clots I think. Mild cramping currently.
Is this normal? Any experiences? 
Haven't seen a Dr because I'm so early and they can't fit me in today. 😳
