i had sex on the days with the hearts (see pic). i used a condom from start to end every time and it never broke or came off.

i also used VCF (spermicide film) in conjunction with the condom on the 6th. According to my app prediction i am supposed to start my period in 8 days. for the past few days i’ve had some cramping and my breast’s have felt sore and sort of heavy. they do usually tend to feel sore when i press them before my period. ik it’s early to test but i took a test with my morning pee on the 12th and this morning (15th). both were negative. i was just wondering the possibility of those symptoms being an indication of pregnancy and if so , would i not get a positive test?
