Weird Early Pregnancy Symptoms?

Heather
With my first pregnancy I had pretty normal symptoms but they didn't appear until after what I thought was my period. I cramped and then bled a lighter than normal period but still relatively normal period. 3-4 days after "AF" I started having to pee a lot and my boobs pretty much grew over night. My son is almost 3 now and we are ttc again. We are on cycle 4 and AF is due tonight or tomorrow morning. I normally spot 2 or more days before AF and this cycle I haven't spotted at all. Also tonight I didn't feel sick at all but had really watery diahrea out of no where (not normal for me unless I have a stomach bug and I don't think I do). And both the corners of my mouth are cracked and really sore and have been for 3-4 days and I never have that either. Are these weird early signs or am I looking too hard? I would test now but I think FMU would be better tomorrow and my husband isn't here to test with me now.
