Help Ease my Mind?

Had sex during ovulation (with a condom) that broke, but didn't realize until we had finished. Took plan B within 15 minutes, but ended up with an Ectopic pregnancy. Had to have surgery to have it removed, only the mass was removed not the ovary or the tube. 

A month ago:

I had the Mirena IUD placed, and starting a few days later I had doubling pain in my abdomen, it was terrible. The doctors ordered an ultrasound that wasn't for a month (sadly) which was today. Since the IUD is 99.9% I have been having "unprotected" sex, no condom. 

Today:

The ultrasound is to check if there are any surgical complications or if the Mirena has shifted. Halfway through the ultrasound the nurse asked me "when was your last period?" And sounded kind of nervous. (To clarify, I do not want to be pregnant.) she asked this a second time because she forgot the first. I am only slightly freaking out, and I get my results tomorrow, just wanted to see if I could get some good vibes to help ease my mind that it is nothing bad.

(My last period was about 2 weeks ago, no pregnancy symptoms: no tender breasts, no nausea, no cravings)
