i had sex on the 15th of Feb i think and i had my period on time. it seemed normal. now however i'm frequently going to the toilet and my breasts feel heavy nd my stomach feels funny. my friends say it is possible to be pregnant even though i had my period? we used a condom but i'm unsure if there was leakage. could i be freaking out for no reason? i am not ready to have a child at this point in my life
