Oh hun, I know how your feeling, I bled at 4.5 weeks in this pregnancy (I didn`t even know I was UTD), I then had blood mixed in my CM last week at 6 weeks, then last night spotting again, it`s all very scary, my OB will not do a scan till I`m 8 weeks, he has checked my HCG levels which he says are very good.

Good Luck
