Early pregnancy spotting

Ashlee
Found out I'm pregnant on Sat. Since the I've had episodes (lasting a couple hrs) of spotting. Basically when I wipe there's red blood tinged mucos, pink or brown spotting. Today I've been having cramps but I'm also feeling very nauseous and the cramps aren't severe. 
Heading to get bloodwork now and then again in 48 hrs to see if levels are increasing. Trying not to freak out
