My period was suppose to start yesterday but it didn’t . But I’m scared i could be pregnant ... I had sex the 16, and we used protection and he never came in the condom (never came at all), and we put water in the condom to check and see if there were any leaks which were no leaks. Should I be fine ? The symptoms I have are, sore breast, some what light cramping, bloating, hot flashes , emotional etc.
