possibly pregnant?? help???

I noticed I've been super hungry which isn't normal for me, Im one that doesn't like to eat and when I do it's a small amount and about once a day) plus some things that I usually find gross taste good like canned ravioli and spaghettos, I'm super moody, and yesterday I noticed I was spotting a light amount, along with a light amount of brown discharge, all I know are possible signs of pregnancy... however I just had a miscarriage in October, is it possible for me to be prego again so soon?? My breasts aren't tender, and I haven't had too many spontaneous cramps, but that's normal for me sometimes... should I go ahead and make an appointment with my doctor?? Or am I just getting my hopes up? I took two dollar store tests day before yesterday, both were negative. My SO and I had intercourse on day 18 and 19 of my cycle, during ovulation and it is now day 24 I believe.
