my period last month was very light. ive put on weight, all i want to do is sleep, feel nauseous, breast are tender and people have made comments they have grown. im 18 years old, have been on the contraceptive pill for 3 years and my boyfriend and i have been together for 2 years. i take my pill correctly although he doesnt use protection and ejaculates in me. i am aware of the situation i put myself in each time, and we have disused it and are prepared to take the consequences if they were to arrive. my next period is due next week im unsure whether to have a pregnancy test or to wait it out???
