Hello, my name is Shelly and I've been seriously racking my brain about weather or not I could be pregnant! So here for the last 2 months, my periods have been off. Last month my period was a week late and only lasted two days...this month it start off as brown discharge that lasted for about three days....then for one whole day nothing....then I start bleeding for two days now nothing again...! I feel nauseous from time to time...my nipple have been sensitive and side of boobs are alittle sore...and I've been craving some certain foods..! I took three home pregnancy test and they all said NEGATIVE! But I was told you can have false negatives....so please help me figure this out!?!? Is there and possibly WAY I could be pregnant or is something else??
