bleeding

Only the day after the embryo transfer, i started bleeding.  (red blood).  I thought it was all over.   went to bed and woke the next morning and it was gone but turned into brown spotting.
rang the nurses and they said it could be the irritation inside from the transfer.  Today i have had a few brown spots. 
symptoms - Pain in breast, blue vein in breast, bubbles popping in tummy.
