My doctor prescribed me metronidazole vaginal gel 0.75% to take once a day for 5 days, during the second and third day I had a white and pink discharge with something that looked like little pieces of tissue ( in the third day I had a very bad cramp and when I looked something came out that looked like a small pink egg), and now on the 5th day I’m having a white and brown discharge that looks like cheese I’m still feeling a little bit of cramps but it’s not as bad. Is this normal or should I look for a doctor? (I do have an IUD on and I am diabetic I’m not sure if that affects how the medication works)
