Paraguard copper iud

So I’ve been on paraguard for about 4-5months now.. first 3 months I got a regular period nothing heavy like they say the copper one makes heavier crampier periods.. the last month It was about a week late and only light period that lasted about 3 days.. and now this month I haven’t gotten my period at all.. I’m late 4 days.. i made an appointment to have myself checked out and have it removed.. anyone else had any problems with it? I’m kinda nervous cuz I’ve read u can get pregnant with it and idk what to think.. my son is barely 8 months 😰
