So my ex was fingering me not too long ago and he decided to go a little aggressive and he put in three fingers and just went on until we saw blood and stopped. Ever since when i Iook for the strings I won’t be able to find them unless I go all the way to my cervix and look around. Please tell me if that’s normal or not. I’m really freaking out. Ps I got my iud in a month ago
