Bleeding after sex?????????

Sailor

I HAVE SKYLA Okay so I got my IUD about a month ago and waited a little over a week before I had sex again. Now every time my boyfriend And I have sex I bleed. its not like thick period blood but it’s definitely noticeable and sometimes will be in my underwear when I go to use the bathroom. Is that normal? Is bleeding a normal thing when you get the IUD put in?
