Missed period

Sherry

So I had an IUD removed a few months back, and I’ve had a few normal cycles since. However I’m now over 2 weeks late for my period! I took 4 different tests over the weekend(from two brands) and all came back negative. Has anyone else had a normal cycle after iud and Then had it change? Or has anyone else been pregnant and had that many negative tests? Please share any insight!!
