This is embarrassing but i lost my virginity to my boyfriend 4 days ago. and we used a condom. lately ive been feeling nausea and my lower back sometimes hurt. could i be pregnant or am i overreacting . my period doesnt come for another 3 weeks . ?

Could be either: It can be hard to tell if a woman is pregnant because some symptoms seen in early pregnancy can also happen in non-pregnant women. A home urine pregnancy test gives a reliable result by about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. Life is full of surprises, so couples must always be ready to raise a child... but condoms work well.
