I got the Paraguard put in after hating the nexplanon (arm implant) and the pain was so excruciating. The measuring part hurt but was kind of bearable...the actual insertion is a different story. Once she was placing it in I was cringing the entire time until I fainted from the pain. I woke up so confused but luckily it was already in & the worst was over. I had mild cramping for a few hours after the insertion & got my period as well. Didn't last long and wasn't heavy. It was worth the pain honestly. I've already lost two pounds (gained 17 from the nexplanon) and I feel normal and not so hormonal!
