Birth control

So ladies just a little info if you're planning on getting on bc or wondering about it. I'm 17 years old I weight 200 and I am on the implant it's in my left arm and I've had it since May 20 and almost a month after getting it I started a period and it lasted for almost a month. Yes you will gain weight I have , but it also has to do w you and what you keep. I recommend walking/ some sort of excerise if planning on getting it. Also I got it on my own w my family doctor , but my case is confidential so my parents can never find out. I could go in w anything to do w my vagina of I have a. Hit or whatever the case is I'm also covered.
