As i was saying about the shower after i did it my stomach hurt but let me get this straight i do not put anything inside there i am a virgin and as i was saying my stomach feels full i sleep alot i feel sick and i am constipted i know this is stupid but could i be pregnant even if i didint use anything inside me ? Maybe there was sperm on the bathtub before when someone was using it and when i got the orgasm maybe some got inside ? Im so worried quick answers please :) Thanks karolina >3
