I just feel it's over

This afternoon I wiped and there was a spot of bright red. Nothing after that, but later around 6:00 I wiped and there was pink and then an hour later there it was again.
My symptoms were tender breasts sensitive nipples and slight nausea.
My breasts got sore later in he day and I couldn't tell if the nausea was anxiety or morning sickness.
My doctor sent me in for more blood work but I never got a call back.  
I've had bloating and light cramping. 
I just feel that it's over. 3 miscarriages and now going on #4.  I just want our baby!!! Why can't it be our turn!
