Actually i had sex for very first time without any protection, we had almost 3 times on first day and then 4 times after 5 days. Even once we used condom on second time but I think the condom was bad quality so it burnt. But after someday almost 20 days later .I am not having my period ,it is delayed for 4 days and not only that .I am having swollen clitoris and i feel like peeing but not able to and when i pee it pains.I am very worried am i pregnant or is it some infection or what. I can't afford to go to and consult any doctor right now . At the end of day when we had sex i was completely exhausted and even felt a bit pain and even i think i had more sex than i should , is it due to that or is it infected or am i really pregnant ,please help.
