Hi, i m 21. I had my period on last month, june 24th and my period cycle is about 35 days. I should have my period come on last 29july but it doesn t. And i didn t do any sex either. Lately, for the last two weeks, i had the trouble of vomiting right after eating as I am now trying to lose weight (yes i did cut down). So, the rule of chances of getting pregnant can be ruled out or not? And, is pregnant only be occur by sex only? Curiosity falls and and i am trying to find answers desperately. tq
