So I woke up with a migraine today and stayed home from work. Threw up a couple times and have been in bed (I've gotten these before so wasnt too worried). Well AF is due Tues 8/18 so I decided to take a clearblue (bfn). But when I wiped there was some watery light brown/pink blood! I never get my period early.. Now its gone and can only see a dot if I kind of stick the TP up there (sorry tmi). Could that be IB? I feel random pinching 3 days ago but am just so confused....
