Hi, I had the Nova T IUD fitted yesterday. It was painful and I had to come home from work due to the cramping pain. Today I noticed a large amount of white to yellowish discharge even though I took the antibiotics I was given with my fitting. I am not sure why i was given antibiotics as I am 33 years old and in a long term relationship. I have no spotting but still cramping pain even though it is subsiding. What is going on?
