Right, had unprotected sex few times. Period late by 18 days but I used to be late practically all the time before I started having sex. But I have been feeling sick lately and it kind of come and goes. I've also been getting random sweet food or sour food cravings. Also took 3 cheap tests and one clear blue test all came up negative. And as far as I know my boyfriend always pulled out when we didnt use a condom. Last time I had sex I also got a really bad pain in the right side and when I read about it it sometimes happens at early stage of pregnancy.
