Cycles getting longer after cluster of early losses

Surprise surprise I've been pretty slack when it comes to follow ups after the "we're so sorry" ultrasounds.

Slowly over the last 6-9months my cycle has been getting longer. I've gone from the textbook 28 days up to a max of 36 and average of 33 days.

It all seems to tie in with a cluster of really early losses (chemical pregnancies) and a later loss.

I haven't put on weight, I'm turning 28 next month so I'm trying to piece it all together.

Do you think they are possibly related? What could it be and anything in particular I should ask to be tested for? (if I ever happen to grow a pair and make the appointment)

I think it is definately possible, although I don't know why - maybe a slight hormonal imbalance?
My cycle after m/c have been all over the place however after IUI they have been fairly close to 29 days, which I think is related to the hormone I was injecting....

It would be hard to pinpoint anything without bloods tests & u/s.
