confused .... rainbow maybe

So I need all the baby dust that can possibly be given . Over the last week or two I've been feeling real tired tender breast and now a little sick at the most random times. The same feeling I had last time  . We lost our little girl in January at 21 weeks so this will be our special rainbow baby . But I'm also confused because I've been trying to track my ovulation with Clearblue digetal reader and it keeps coming back with unable to ready so I also took the digetal pregnancy test -first response and it comes back to the ? .. AF is due with in the next week or so I'm hoping it will stay away but confused by all the feeling or maybe it's my emotions I just don't know anymore o feel broken and confused ..... please send your dust and advice !
