Is pregnancy a good possibility or no?

So I was supposed to start on Wed June 15 but I have been up to 2 weeks late before but this time is different. On the 13 & 14 I had some light spotting so I thought I was starting and used a tampon but it ended up being dry. Then a few days later I had light cramping and thought I was about start but I never did. It is now the 24 and 2 wks late will b the 29. I have the paraguard iud which has no hormones so u still get ur period every month. Im just looking for advice on what u might think could be going on. And please don't be rude. Also this may b tmi but here lately I have been wanting to have sex like every day and that is really unusual for me. Idk if that means ne thing or not. Thanks for ur input.
