I have been TTC for a couple of months now with no luck...I started to take pre-natal vitamins, and laying down after having sex with my legs in the air...my last period was on sept 9 2010 and im due for my period on the 6th of oct.. i have been having aching breast and restless nights..ive been feeling nauseous but not enough to vomit or anything just enough to bother me and be picky on the things i will eat..me and my husband had sex last night right before bed...i laid a tissue on my vagina so i wouldnt leak out in the middle of the night ( almost like using a pad ) the next morning when i went to the bathroom the tissue had a very light brown color on it..it doesnt burn when i urinate..or even have a smell..when i wipe it doesnt show up but i stick my finger inside and its there..doesnt come out when i urinate..im really paranoid that it might be my period comming...but i have never experianced this BEFORE my period..is this another sign of pregnancy?
