Hi I'm 17 Years Old. I Just Got On The

Hi I'm 17 years old. I just got on the Depo shot on March 31. And I'm taking metronidazole and nitrofurantion becuase I have uti and BV. but before I started those medication I been noticing mild cramps coming from the uterus and also 1 Secound sharp pains on the right side where my right ovarie would be. Also my uterus has been throbbing alot. And u can actually see it pulsating alot. And at night the pulsating gets even more intense to where my parter can point out exactly where it's pulsing from. is this normal ?
