Im not sexually active yet, and my periods are never on any specific day, and I sometimes skip months from time to time. My boyfriend hand his hand near my vagina and had precum on his hand before touching me, yet he whiped his hand on other things before touching me directly there, plus I havent broken my hindmen yet, and havent done much sexually, but pregnancy is something I fear since im only 15. Is this something to be concerned with? Or am I worrying about nothing?
