LADIES PLEASE HELP!!! No AF after miscarriage???

Its been 94 days and counting... No AF and BFN week after week. We are TTC and I've been checking for ovulation which happened 3 weeks ago and nothing is happening. :-( Periods used to be every 6 weeks prior to miscarriage.
 Anyone else experience this? I'm going to see a new gyne this week since my last one has not given me anything other than "it's normal" responses or "it'll regulate soon" (which totally doesn't seem normal!!) super frustrated right now. I need some positive vibes sent my way.
