Heavy spotting after an IUD?

Mackenzie
Ok so I got the Mirana like last week and had to be on my period to get it put in... But now I'm spotting pretty heavily... And I just got a new boyfriend.. (I'm really shy when it comes to stuff like this) and so I keep turning down the sex and when he asks why I don't know what to say because I don't want to discuss with him so two questions... Is it normal to spot heavily after getting the Mirana (IUD) and what should I tell him?!😭
