Hey, last month the 26th of October me and my boyfriend had unprotected sex, however he pulled out, i did not realise until after that this was the time i was ovulating, i have had extremely sore breasts since about a week afetr which i usually get for my period, hoever they continued, and i am using the bathroom more frequetly, i had a very light period for about 4 days (very unusual for me) it also came 4 days earlier that usual.I experience naseau but only sometimes…. i took a test 4 days before my expected period it said negative, i am still feeling sick sometimes, and i have an increase in vagfinal discharge is there a possibility that i could be pregnant?
