BC opinions


So a little back story wen I was in high school I went on the pill to try and control headaches and to regulate my period well it didn’t help with my headaches it did regulate my period but I had terrible cramps (never got cramps before) so I decided to stop taking them. So now I’m pregnant and want to go on birth control after I have the baby cause my fiancé and I do not want to get pregnant again right away so my question is should I just try a different pill ( which I am terrible at remembering to take pills even my prenatals) or should I look into other options I will not the the implant in the arm but maybe an iud just want peoples opinions on different birth control methods.
