So me and my boyfriend live together and we used to be very careful about sex, I went off birth control back in november and since then my periods have all been normal and like clockwork, until now. I was supposed to hit my period on monday but it didn't come, I've been feeling sick all week and my boobs are very sore, also I have been getting heartburn though I don't eat spicy foods, and the lower part of my tummy has hardened and just feels weird. Am I going crazy or am I really pregnant? I took two at home tests this week but both were negative...is it too early? Today I started cramping a lil but instead of my period its a brownish discharge?  We have sex almost every day and like I said we have started getting pretty careless about protection, I also read somewhere that sperm can stay alive for up to 3 days after intercourse, is this true? Please someone help me!

yes sperm can live 3 to 5 days in the vagina. Also sometimes periods come late from all kinds of things like loosing or gaining weight and exercising, stress. I've had my period 2weeks late and me and my friend were play fighting and he hit my in the stomach and i came an hour later. If you dont come on in another 2weeks then take a test to see good luck.
