Long cycle caused by miscarriage?

Just thought I'd start this thread to see if anyone is in a similar situation. I'm TTC #1, been trying for over 7 months. Had two miscarriages one after the other. All natural, no D&C. Right after my second miscarriage, I noticed that my cycle is suddenly really long!! I am now on Cycle Day 36. No period. I don't know if I ovulated. No consistent CM. On cycle day 28, I had the stretchy rubbery CM kind--similar to rubber cement when it dries. After that, dry up to this point. On cycle day 29, the doc did an ultrasound and said she found a mature looking follicle. As of today, BFN.
