I think that's how you spell it lol
So I got mine on October and I guess I'm not like most people because I didn't bruise AT ALL when I got it put in and I have not had my period since I got it.
All I get remotely close to periods is really gooey spotting for like an hour around the time I'm supposed to get my period but even that stopped after 2 months. 
Is that normal and is anyone else going through that too? 
Any help is helpful lol thank you
