Blighted ovum .. No period yet

I was diagnosed with a blighted ovum on January 18th at a very early 5 and a half weeks. My boyfriend and I have been trying since last March so we were so excited to find out. I lost it naturally over the next 2 days or so and proceeded to bleed for almost two weeks. Still no period. It should have started the beginning of last week. Has anyone experienced this and how long did it take for you to get it back to normal ?
