HPT negative but still not period 😳

Marianela
In January I did my first <a href="https://glowing.com/glow-fertility-program">IUI</a>, this one did not work, got my period 01-25-16 and that was the last time. I did have some spotting middle of February but that's it. I did two HPT that came negative. I am about 12 days late and I have never been late, My period is not irregular, I am 32, do you think could be just my new normal because I'm over 30? 
Have this happend to you?Â
