okay well, about 31 weeks ago i was fingered by my ex an i was worried about the precum. i took a test because the stress made me miss a period. the test was negative and i have had regular periods since and still do. but, at the beggining of january 2015 i started feeling really bloated without a change to my diet. since then i have been paranoid that i am pregnant and diddn't know. I diddn't go to the doctors at first because i just thought i was being stupid as i had apsolutally no pregnancy symptoms an i diddnt look the pregnancy stage i was supposed to be in. I know im being stupid about the pregnancy because i have taken 3 negative clear blue tests, have had all periods (they have actually regulated out in the past 3 cycles :D ), and have had no symptoms including not being massive. i went to the nurse last week crying and she basically laughed at me :). 

HOWEVER

i am 16 and literally NEVER ill, i am class 1 obese just i am almost in the overweight category but still i am probably one of the healthiest people in my school :). but still i am worried about my stomach. it is bloated almost constantly and the only time it even slightly stopped was in the school holidays :( then it came back which made me think it was stress. but recently i have also been noticing a sort of pulse in my stomach. it varies being hardly at all to really bad :( i have had slight constipation which comes and goes really but its never really really bad tbh. also i have been feeling more hungry more often recently without a change in my diet :/

please can someone tell me that im being stupid about the pregnancy thing and also tell me that either you have the same trouble as me or you have some miracle cure please I AM FREAKING OUT
