my period was expected on February 2nd but on the 27th january i went to the bathroom and when i wiped i saw brown so i put on a pad but for the next two days i only saw brown when i wiped,the most i saw on the pad was a dot . then yesterday (15th february) i went to the bathroom and the same thing happened,even this morning,a little brown when i wipe but nothing on the pad. and for the past couple days i have been extremely exhausted,all i feel to do is sleep. i've been feeling nauseous for the past two days and very emotional and moody. i did a pregnancy test saturday night (9th february) and it was negative,i don't know if it was because i ate right before i did it,if that would affect it. but please can someone help?
