Ever since i got the iud i've had minor spotting as my period. well i had spotting two days ago and i had intercourse today and bled a lot!!!! and now i'm back to no spotting. is that normal? should i be concerned? that's never happened to me before?

Spotting or irregular bleeding is common with the IUD. It may improve over time. Consider touching base with your primary care doctor or whoever placed the IUD. It is always a good idea to rule out other conditions that may cause bleeding, as well as pregnancy. Short 5 day courses of NSAIDs can be considered to reduce spotting, but speak with your doctor before embarking on treatment by yourself.
