ok so im on the birth control called nuvaring and i took it out for a week for my period then that following sunday i put it back in and the next day i had unprotected sex w my boyfriend....it has been almost 3 months now, i get my period every month tho, but my stomach has gotten bigger and my apetite hasny increased or anything, i just get cramps a lot and pee more frequently and im bloated often...will taking a pregnancy test still b accurate for me even tho im on birth control and still have my period?
