Feel like I’m on my period, but no blood

I got the IUD about a month ago. I don’t know if anyone else experiences this, but let me know. I almost always know when I’m about to get my period. I get the typical signs of pms. Tender swollen breasts, moody, feeling oily, crampy(etc...).

I was suppose to start my period last week, but I didn’t. Although I’ve been experiencing what it feels like I’m on my period. (Tender swollen breasts, moody, and I even am getting what feels like period cramps but I’m not bleeding at all!?)

Does this happen to anyone else?
