Can you ring the hosy and ask them, they may have someone on how can check for you, it is quite possible that it is some break through or bleeding from the cervix.
On top of what has happened with this pregnancy, lots of bright red bleeding, 3 major bleed and then on and off for about 5 weeks, I also bled for 2 weeks with DD and she is here making a big mess of the tupperware drawer next to me

I so know how you feel about going to the bathroom, I completely understand your fears, I still have them myself .

Oh hun if I could I would make a nice hot cuppa, give you a block of chocolate and give you a big hug right now. Rest up lie on the couch and try to watch some crappy tv with a cuppa tea.
