patch birth control and periods

Kim

so I've had the patch for about 4 months now as a birth control, and I started to notice my periods were getting a day shorter each month. will it stop me from getting my period eventually? another question I wanted to get the depo shot for the 3 month summer because I won't be able to hide my patch in swim suits, but I've heard so many things about it. any tips or help and answers please!
