So I'm suppose to get me next (2nd) depo shot within 2 to 3 weeks from today and since the day before yesterday I've been getting random waves of neasea. They are sometimes really all over the place in a day but I usually get them when I wake up whether it's 6am, 10am, or 2pm, & etc. about a month ago I also started getting slight cramps for no reason. I'm not sure if it's the shot causing this or what but does anyone else get these symptoms?
