REST!!!!!!!!
And see if there is any pattern to the BH still.

As for having a Dec baby. My girl was born 14th Dec and for me i love it coz' all the cool new toys etc are out so she has such a nice variety of choices and gifts!!
But try aim for full term if babs' will let you.

If increased temp and Bp is due to an infection and it's still there in 2 weeks i'd prefer not to irritate the cervix or increase the chance of more infection by having an internal.
If there has been a prob with the cervix in the past you might wanna find out all your options as to what would be best.
But you decide,
If you feel it might be worth having an internal to know if anything is going on and maybe having a check could put your mind to rest then you can, choice is yours.

I did have a lady who had to have a stitch put in to help keep cervix closed for the pregnancy so you need to decide what would be best for you...

thanks for the update... keep us posted
