Late with an IUD Paraguard

[crookedYoung]

I got a paraguard IUD put in (copper coil) last month (on May 14th), I bled a lot when they put it in and experienced quite a bit of spotting till the 26th ish of May. Normally I would've been due around June 5th ish, but I'm late. I took 2 pregnancy tests and both came back negative. One last week on Friday and one this week on Tuesday. Is it normal to be this late and not be pregnant? I'm not having signs of pregnancy, no puking no sore boobs. I do have a bit of cramping and have had it for the past 2 weeks and I've been getting the normal signs that I'm getting my period but no blood. For example, I normally get really bad car sickness whenever I'm on my period. and that's been happening lately.
