I take birth control, and i have for like three or four years now and i've had to switch cause it was ineffective or whatever before and like four weeks ago i forgot to take it for a few days, but before that i was having the signs that i had before when it wasn't working and i called the ob gyn and he said from the signs i was saying he said it sounded like it wasn't working and my boyfriend and i had sex a bunch of times without condoms and lately i've been feeling really sick after everytime i eat and i'm pretty tired like all the time...is there a possibility i could be pregnant???
