Seriously? Roseola AGAIN!

Yes, I know I've posted a similar topic before. But Landen had a 101.5 fever today, but acted fine, so I just gave him a half dose of motrin and it brought it down. Tonight he woke up from sleep, shivering, with 103.
Now, this is probably time number 9 that he has had this. The ped. told me a while back that its rare to get it more than once, but at the same time he never tested to see if its exactly the roseola virus. He said it could be something else that presents itself that way (fever for about 5+ days-in our case, rash for 2). His fevers are worse at night, and there are not really any other signs that he isn't feeling feel, except maybe a little fussy. So, when I bring him to the ped. we have no choice but to check his urine, then send him for bloodwork, and everything comes back fine, and by that time, its gone, and the rash has appeared. So, after maybe 4 times of bugging the dr. with this, I decided that I would just take care of it myself. I, of course, watch for other symptoms, but really none come. The ped. always recommends that I rotate motrin and tylenol every 3 hours. I do at night, but during the day, I just play it by ear, or by temp rather.
They say its contagious only when they have a fever, tho, and I respect that, and other parents, but at the same time, the times he has been around those other kids with this, they never got it.
My first thought this time was, uh! I'm pregnant! I looked it up, and if the mother has never had it, or come into contact with it/developed an immunity, then there is a slight chance (very slight) of miscarriage during the first trimester, and congenital defects later on. B/c Landen has had this so many times, I'm not really concerned that I haven't developed an immunity to it, but I think I will give a call to my Ob tomorrow just for kicks. :)
Right now, at 2 am, Landen requested a popsicle. (I made-half juice half water) It appears the motrin wound him up, and I couldn't get him back asleep. Hopefully the pop will help with the temp. (I also did a luke warm shower).
B/c I have that live feed, I saw that many people have done a google search, and came to my last post of Roseola again, and that was not at all informative, so I hope that I have helped some who are in a similar situation.
Now, lets hope we get some sleep and feel better soon.
