Ovulation post-birth control

Morgan

Y'all, I got off birth control in January and have had 2 or 3 periods since (I cannot remember for the life of me). My husband and have just decided to become pregnant a couple days ago, yet my periods are so irregular that I have no idea when I am ovulating. Should we just have sex like animals and hope for the best?? Or should I base it off of my cervical mucus?? Please help!! Any info is good info!!
