Question about wacky cycles off BCP

We all talk about how cycles can be wacky coming off BCP. Does this mean you can also have a short LP one month and it not be cause for alarm?

I got what I considered at the time a pos OPK on CD 18, definite pos on CD 19, possible pos again on CD 20, and still a dark line but maybe not AS dark on CD 21. I have been using CD20 as O day which would put me at 8 dpo today and I feel her coming. (I had a 30 day cycle last month.)
Should I start being concerned about a short LP or can you have a short LP for just 1 month?

i wouldnt worry - everything is out of whack your first month off (at least thats what i was told). Wait to see when AF actually comes and then also wait to see what happens next month.

My personal experience this month was very similar...i had a positive opk for almost 3 days and 8 days later i would have sworn AF was coming...but she didnt come until 13 days later which means my LP was right on track.

This will be my 3rd AF off of BCP. First cycle was 30 days. But come to think of it, when on BCP I only got AF cramps day of AF and last month they started 3 days before so maybe I will end up being 10-11 dpo. It's still a little on the shorter side but not terrible I guess.
