bright red bleeding 4 days after hsg???

Is this normal??  I had very light spotting the first 24 hours after hsg, then nothing. It's now been 4 days since the test, just went to the bathroom and when I wiped I had bright red bleeding, as if my period started but I'm only CD 9.  It's too early for it to be ovulation spotting for me. Should I be concerned???  No fever, just a sort of bloated feeling.
