Late, like really late period after removal?

Evette

I removed my paragard like 2 weeks ago (January 28) and my period should’ve been here the 8th of February but I have no period and no symptoms of my period coming soon. I had gone to the clinic a day before my period was “due” and they did a pregnancy test, it came back negative. So I’m wondering if anyone has experienced this after their removal. Or if I should wait and get another pregnancy done. I haven’t had sex since the removal. But I did have sex 8 days before removal. Should I be okay?
