my boyfriend and i are started making out and got carried away by rubbing our bodies against each other (and private parts) whilst doing this. we were both fully covered. he had on jeans and boxers and i had on my underwear and a jeans. i do not think he ejaculated but i'm sure there was precum involved. this incident happened 2 months ago, yet i have got my periods both the months although the first time it was 5days late and than 3 days late.. i have also been suffering from nausea that lasts till the night, abdominal pain n frequent headaches..i have been too scared to take a pregnancy test. do you think there could be chance of me falling pregnant this way.. the nausea and headaches keep getting me worried. please help x
