AF after stopping BC pills

My husband and I recently started TTC. I stopped my BC pills (I was taking Vestura) on 05/28 and had AF 06/1. I should have AF the end of June but still nothing. Before BC my cycles were on average 29 days. I got a BFN on CD 35, it's now CD 38 and still no AF/PMS symptoms. Is it normal to have longer cycles after BC?
