Wow Little Mis Sunshine i am having the same thing at the moment. I have had consistent BH in the top of my uterus and then also have diahorrea, but finding that it is a push to come out rather than just flow (SORRY TMI). I have been constantly feeling sick in the stomach and feel like my morning sickness is coming back (as i have had it really bad at the beginning). My problem is i don't think i have dropped and bub seems to pop in and out of pelvis. I feel like if i gave one huge push so that i could break my waters things might start happening but of course it doesn't work like that. I also have a little nigglinging in my side and back but not much. I jsut think mine might be Gastro.
Goodluck with everything and i hope your little man will hang in for you for the next few weeks.
