So i lost my virginity two weeks ago, and ive just had my period (it came when i thought, on my normal cycle) ive had my period for 7 years so its never really irregular, it only lasts 2-3 days, but lately ive been really worried oncase i may be pregnant, i never used protection but it never lasted long and he pulled out very soon, so now ive been left rattling my brain to what i have to do, im 16 years of age, nearly 17, so i cant tell my parents so i dont know what to do? Am i pregnant? Ive also had a sore stomach the passed two days but i think thats either trapped wind or stress due to what ive done, please help!!!
