Off BCP after 13 years so nervous!

Hi everyone. So I’m turning 33 soon and have been on birth control since I turned 20, loved the seasonal pills and only 4 periods a year but I’m married now and finally ready to start a family so I just finished and threw away my LAST pill pack! Should I start tracking immediately, or wait until I have a few regular periods and make sure “everything is working”? No idea what to expect so friendly encouragement and advice is appreciated! Wish us luck!
