Help l cycles changing after 1year ttc ?

Jade

Hey ladies

Af kindly f-ed off 2 days ago and today cycle day 7 (periods only last 5 days always have) i had back ache (normally my sign ovulation is creeping up) so i took an ovulation test (please not it is much darker is person than the picture its the damn lighing in here) are my cycles changing ? Do you normally get a lh surge after a period ? Or is this going to be an odd month out? Any ideas please let me know xxx
