Pregnancy?

kaylea
Is it possible for me to get pregnant while on the pill? I have been cautious and still taking my birth control but i taken 2 test and it came back negative but i been having morning sickness, tender breasts, cravings, stomach pains, sneezing, high sense of smell and taste. Someone please give me good advice to what im going through. Im confused and scared that the test is wrong that i am pregnant.
