If you have so much trouble taking the pill properly, you should think about going back to the GP and requesting an implanon implant instead. Once you get the rod put in your arm, you can forget about it for a few years.
Seriously, if you took the pill wrongly this time, it is extremely likely you will do it again. That's why so many young girls are pushing prams! Get the implant and save yourself the grief.
