New to this site, one miscarriage, hypothyroidism.

Well I thought I would try this site, keep up with tracking... I'm 28, 2 kids from a past marriage and in love with the greatest man I know. We are hoping for a baby of our own, I did get pregnant in nov and had a 8 week miscarriage, took 12 weeks to get period back and we continued with trying with no luck yet. I do have hypothyroidism And I do take synthroid for this..... I also have 36 day cycles, part of me feels as though I need to find a way to shorten my cycle to at least 30 days...... It's so frustrating of a wait, it kills me. So hello ladies, any advice is very much welcome.
