I'm seventeen years old and have a very irregular menstraution cycle (sometimes 3-6 months apart) My mom and I are looking into birth control to regulate and we have lowered my options down to 2: the implant or the patch. If you could please tell me what you think would be the best for me, or what has worked for you please let me know. My biggest concern is spotting or the patch falling or coming off while sweating or playing sports. Is that a possibility?
