Two things weighing heavily on my mind...

First, an update on Logan.  His temp hovered between 100-101 today, all day.  His mood on the other hand was wonderful! He's his playful self.  We went to the doctor yesterday, and he said he was almost positive it was viral (although his throat was red, so we did a strep test...negative)
He said that due to the really high temp hitting so fast, chances are it was one of a few things.  Roseola, Hand foot and mouth, Fifths disease to name just a couple.
Apparently, in all of these you get the fever right away, and then when the fever breaks, you get a rash that will basically let you know what viral infection he had.  Once the rash appears, he will be basically symptom free.
So...that leaves me with the one thing thats on my mind.  Fifths Disease is also called, 'slapped cheek' disease.  That is what appears after the fever.  It looks as though the child was slapped.  Well...this afternoon Logans cheeks were getting mighty pink, and by the time he went to bed, they were very pink.  I'm praying it was just due to the fever being here for 48hrs.  Fifths disease isn't a good thing for a pregnant woman to be around.  While my doctor assured me that half of all adults are immune to it because they got it when they were children, it didn't make me feel all that better.  Here are some things I read about fifths and pregnancy:
------------------------------
Fifth disease has been documented as a potential congenital infection of the fetus. If a pregnant woman becomes infected with parvovirus B19, she may have no symptoms; however, the fetus may suffer damage, including the possibility of stillbirth. In women who have fifth disease during pregnancy, there is about a 25 to 35 percent risk that the fetus will become infected.
Having fifth disease rarely causes birth defects or brain damage, but can lead to early miscarriage or stillbirth. Most miscarriages due to fifth disease infection happen 4 to 12 weeks after the mother's illness begins. The risk for stillbirth is 5 to 10 percent. The greatest risk for pregnancy loss occurs with infection during the first half of the pregnancy.

FAQ's
What risk does parvovirus B19 infection pose to the fetus?
Fortunately, most fetuses are unaffected when their mothers contract the virus. However, when a fetus does become infected, the virus can disrupt the ability to produce red blood cells, leading to a dangerous form of anemia, heart failure, and up to a 9 percent risk of fetal death - resulting in miscarriage or stillbirth.
Fifth disease in pregnancy has not been proven to cause birth defects.
-----------------------------
So, as you see, this is quite disturbing.  Darn internet, I swear it turns an OK situation into life and death.
So, of course, if Logan DOES have fifths, we won't really know until he develops the red rash on his cheeks.  And, of course, if he does have it, its too late for me anyway.  He wouldn't be contagious anymore.  The last 2 days have been nothing but cuddling, loving, etc...so, if I'm NOT immune, I'll probably get it.  I called my OB today, and said we could do a few different things.  Bring Logan in for a blood test (no thanks!) or bring myself in for a blood test to see if I'm immune, then it wouldn't matter.  Or, just wait and see what happens with Logan.  If he doesn't develop it, then of course we are fine.
I chose option 3.  I was not going to make Logan get his blood drawn for a virus. 
So, we'll see what tomorrow brings.
The second thing weighing heavily on my mind...Today I am 16w4d
I have not felt a single movement yet.  With logan, I didn't know what 'feeling' felt like, and I remember like it was yesterday the first time I felt it.  I was laying on the bed with Dave, and Dave had his hand on my stomach.  We BOTH felt it at the same time. What does that tell you? That I OBVIOUSLY must have felt it inside much earlier if Dave felt it the same time I did. I just didn't realize it.  That was 20 weeks exactly.  Now, from what I understand, with your 2nd you feel it much earlier.  I'll be 17 weeks very shortly, and nada! Nothing! Not even a, 'was that it?'
Then, I've been reading the board of women due in January.  I'm due the 1st, so obviously I have one of the earliest due dates.  There are women on the board who are feeling movement with their first child, and they are behind me.
It makes me very nervous.
I remember my friend saying, 'wait until you get like 16 weeks or so, you'll feel SO much more confident then!'
While there is NO hiding I'm pregnant (my belly is nice and round) and we actually could feel my uterus this morning.  It was right at my belly button line.  I'm enjoying this pregnancy, (except for these darn headaches! ;o) but STILL....I'll stop the monotony.  You know what I'm going to say.
So anyway, Keep us in your thoughts. I'm sure its not fifths, but you just never know.  I'll keep you updated on those cute chubby cheeks tomorrow!
