I had sex for the first time which means i lost my virginity on Friday, and from saturday I've been getting the symptoms of pregnancy, i searched for it online and i kinda match with all the symptoms, like headache, backpain, dizziness, cramping (like the cramps on periods), i pee a lot more than usual now, i get a lot hungrier than usual, mood swings, getting over emotional about everything, and we didn't use condom also and im not sure if my boyfriend came inside me or not because according to him he didnt feel himself coming inside me nor did i feel anything, and after he pulled out i gave him a ha****b and he came 3-4 minutes later. So is it possible for me to be pregnant ? When should i take a pregnancy test ? Also, im not 18 yet.
