Hi there, I too was on the pill for 10 years and stopped just under 6 months ago. In this time I have had a 65 day, 87 day and now a 90 day with no signs cycle so my instance here is one where the body takes a while to "wake up" or sort itself out.
Other friends I have fell pregnant missing a couple of pills, so everyone is totally different.
I reckon go for it!
