Help me need advice

Help is this normal??? This has been going on for a week now I just went to gyn Monday for my two week f/u and was told the iud was in place and my uterine wall was very thin I also have been experiencing cramping they are not as bad as they were earlier this week!!!! Should I go to hospital? I’m so concerned I’ve never experienced anything like this before… this is my first experience with an iud

S:b: I just finished taking metrogdl for bv yesterday
