I've been waking up with headaches lately and haven't been so hungry anymore. My boobs were really sore last week and my nipples too. Boyfriend couldn't even touch them it stung so bad. I was crampy and bloated around then too, thought it was odd cause was a little early for my period (which never arrived) not even the slightest bit of spotting. I have some white creamy like mucus but only notice it when I go to the bathroom (doesn't come out into my panties) it does not have an odor or anything. Are these pregnancy signs ???  Also don't know when I should test.
