irregular cycle after MC

I am getting super frustrated by my cycle. Had an MC in August at 11 weeks. Was always very regular before pregnancy (was my first pregnancy). After the MC in September I had a super light super short period, 30 days after my D&C. Octobers period came 30 days later and was also shorter than my periods before. Now I'm at 35 days. I've been testing every day but there is no bfp, no faint line, no nothing. Just bfn. With my first, I got bfp right on the first day of missing my period.

I'm so discouraged! Will my cycle ever go back to normal? Will this period even come? And if it doesn't- what do I do? It feels like there is no way I could be pregnant 5 days late with no positive tests. :(
