Am I pregnant? Only 16 :(

Hey guys so basically I had unprotected sex back at the end of June (June 26th) , i missed my period for July (I did have some light spotting around the time of my July period though) ,my period cane for both August and September with all my usual symptoms but now my period for October is late. I know it’s uncommon to be pregnant and have a period but does anyone think it’s possible that I might be pregnant. I have no symptoms of pregnancy except bloating and nausea. ❤️
