What is Going on Over Here???

Um, can someone please bring back my regular baby?

First, Ella has woken up at 5 a.m. (but fallen back asleep) 3 days in a row, and yesterday, she woke up at 10:30 p.m. and whimpered for about 20 minutes (this from the kid that NEVER wakes up between 7:30 p.m. and 6:30 a.m.).  Yesterday, she only napped for 40 minutes in the morning and screamed bloody murder before finally falling asleep for her second nap (after I went back in her room and drugged her up with Tylenol).  Since yesterday, her nose has been running like a faucet (but she's not sick- no fever, no cough, nothing), and she screams when I try to do the aspirator.  This morning, she woke up with a runny poop that leaked from her diaper and got on her sheets (I think that may have been from giving her whole milk yesterday for the first time).

What is going on?!  The only thing I can think of is that she must be teething...and here I thought we escaped the bad teething experience since all the teeth so far have not affected her at all.  I don't feel any new teeth though so who knows.

HELP ME.

Edited to Add: Now she has a diaper rash on her girly parts!  She has never had diaper rash...not even when she was a preemie and newborn...what the heck???????

Edited Again to Add: So she had another poop that was normal, but when she woke up from her afternoon nap, I had to aspirate her nose about 20 times because there was so much snot in it, and she LOST IT.  Crying uncontrollably and would.not.stop.   She then threw up 3 times while sitting in the family room!  However, I *think* the throw up was crying induced.  UGH.

Edited AGAIN to Add: We took her temp, and she does have a fever...the rectal thermometer is so wacky though...it said 100.9 then 101.9 then 99.9.

And one MORE Time to Add: Before bed, temp was only 99.6 (which is not even a fever when taken rectally).
