Discharge ?? No pictures!

I'm 4 weeks along (according to Glow) and I just started noticing some creamy looking discharge When I wipe. It's not really tinged a certain color that I can tell but I'm just wanting to make sure it's normal. The cramping has pretty much stopped for me now. It only happens every once in a while. Is this all normal?? It's my first pregnancy and I don't want to call the dr unless I have to.
