Spotting Skyla IUD

Arlis

February 15th i got my Skyla IUD inserted yes i went though the pain and now day 3 I’m not longer cramping or feel it. I’m just concerned about the spotting.. i don’t want to ruin my underwear and wearing pads is so uncomfortable (I’m a tampon person). The spotting is light and at certain times of the day worse than others. How long has the spotting lasted for some of you ?

Also How long before i can have sex with my boyfriend again , I’ve been terrified because i don’t want anything to happen.
