Cycle changes after a miscarriage?

Melanie • Rainbow baby girl conceived with the help of science and born 5/23/17, pregnant with baby number 2, due August 29th

Has anyone else who has had a miscarriage notice their cycle change after it? I was pretty regular before at around 29 days, even when not on birth control, but since miss carrying in December, I didn't have one for a while, then a couple normal ones, then one that was like 40 days, and now I'm on this one, where my ovulation tests alternated between low fertility and peak fertility for almost 2 weeks, and should start my period today, but given I was fertile yesterday, I don't see it happening.

Curious about other's experiences. Ttc, and this makes it tough! Thanks.
