Overthinking? Or too early

my last period started 10/09 and i had unprotected sex 10/22. This past week or so my breasts have been super sore and feel heavy, so i took a test 11/02 a day before my new period should have started and it was negative. yesterday i should have had my period but only had very light spotting at the end of the day into this morning. now it’s stopped. i took another test that also is negative. besides sore breasts i don’t have symptoms, except maybe feeling nauseous after eating really sugary food. somebody PLEASE tell me if I’m just overthinking, or if it’s too early too tell. i’ve tried researching and it’s all so confusing lol 😅
