TTC after being on the birth control pill

I’m finishing my last pack of birth control pills this month and am very eager to start trying to conceive! I’ve been on birth control for nearly 5 years, and had painful/sometimes irregular periods prior to that. I know there is no medical reason that I shouldn’t get pregnant next month if I ovulate, but I’ve heard it can be better to wait until after your next period to allow your uterine lining to come back thicker. I wasn’t worried until I talked to my counsellor and she said I shouldn’t be alarmed if I miscarried the first time... I know she was just trying to normalize that possibility for me to lessen the potential emotional impact, but now it’s got me wondering if I should wait. The problem is I’m so excited and I’ve already been waiting several months in anticipation! I want to start trying right away!

I know it might not happen right away anyway, but I’m wondering if anyone has experience getting pregnant right after stopping birth control. Any problems, or success stories?
