Dry heaving almost every day on nexplanon!!

I was put on nexplanon in January.. my periods have been all over the place (obviously) but I have been feeling sick and dry heaving constantly.. it’s like I have morning sickness!! But for 5 months!! Not a day goes by when I’m not constantly feeling the urge to throw up! When i brush my teeth, dry heaving.. when I eat , dry heaving.. it’s not to the point I’m puking... but when it’s bad I do force myself!! It’s really annoying because it’s all day! I won’t even be cleaning up my daughters diaper, the dogs poop.. and I’m just wanting to end it!!! At first I thought it was my anxiety. But now I’ll be fine and wanting to throw up....or I’ll get a tickle in my throat.. it will feel like a cough.. but soon I’ll be over the toilet
