I am late for my period. I was supposed to pick up my birth control last month after i finished my cycle.. unfortunately i kept forgetting and telling myself that i dont need birth control because after my last break up i refused to have sex again for a while.. I found a great guy and we are now dating.. We had tons of unprotected sex all month.. some nights we even did it 2 to 3 times.. I know it sounds retarded that i wouldn't be responsible and take my birth control but i thought i had more self control then i actually did. Im late for my period.. but i ahve taken pregnancy tests and they are negative. Im exhausted but i get plenty of sleep. My nipples hurt and my boobs are sore ( i never get these symptoms before i start my period).. I have constant headaches.. and at times im nauseated but do not get sick.. Sometimes i lay awake at night because i cant fall asleep cause i feel so sick.. I am just curious why a pregnancy test would be saying that i am negative.. i have a doctors apointment on tuesday for a blood test.. my intuition says im pregnant.. but the tests arent showing it.. Do you think im pregnant?
