question

Ok so I had a period last month on the 9th started bc on the 11th. I quit the pill on the 14th the same day I stopped my period. Well on the 24th I started bleeding again and stopped on the 26th. Had unprotected sex trying to get pregs on the 29 and the 1st. Well on the 7 th I spotted two spots of blood and the next three days is wipe and have some brown discharge I finally stopped. I have been cramping for a few days and keep thinking I'm going to start but nothing yet. could I be pregs or no? I has anyone ever been through this?
