Possible?

Kenzie

So I’m on the mini pill norethindrone. I’ve been on it for 10 months now as of yesterday. For a few days this month I took the pill an hour late due to the whole time change thing. Well on the 1st-4th I had my period. On the 8th I had unprotected sex then on the 14th I had some light bleeding going on. Is there a possibility of pregnancy? My breasts have been sore and there was a bit of cramping when I noticed the light bleeding.
