I went to see my boyfriend after 2 years and we engaged in intense foreplay for four days, there was no vaginal penetration but he rubbed his naked penis on my vagina many times, every time he came we made sure he washed up before touching me again, his semen never came in contact with my vagina, my period was due 5 days ago but it's not coming, I don't feel any symptoms of anything at all, am perfectly normal, I carried out the pregnancy sakt test 2 times but everytime I pour in the salt into the urine, the salt just sinks to the bottom and there is no reaction at all, could I be pregnant?
