Pregnancy after Skyla IUD removal?

I had my period from 01/16/2018 to 01/24/2018. I removed my IUD on 01/27/2018. Had sex immediately, and for the next four day, more than 3 times a day. I did bleed a little for about 24 hours; I’m assuming from extraction bleeding. Anyway. I’ve had nausea, cramps, slight bloating, slightly sore nipples, and even some white discharge. And I’ve taken 6 pregnancy tests like 2-3 days before my period was due—all negative. But I’m now 2 days late. Could I be pregnant? Or is my body just adjusting to the IUD removal?
