Hi... I have been experiencing some of these symptoms for over a week now, other for only a day or so. extreme fatigue (10 and 11 hours of sleep now a night), a little more frequent urination, a little excessive saliva (have to swallow more often and when i talk i notice it bubbles in the corners of my mouth *gross*) constipation, bad bloating, i can only eat a small something and i feel so full it makes me almost sick. the areola on my right nipple is darkening. i think i noticed this morning that the left looks a little darker too but the right is still darker and the Montgomery things are raised and it looks like there are more of them. My period was due today, but i am still discharging which is a little odd, normally the day i start or the day before i stop all discharge, i just bit my husbands head off for no reason. I am having this kind of cramping sensation in my abdomen, not really a pinch but it feel different that period cramps and i've noticed it on and off for maybe 5 days to a week.I took a pregnancy test yesterday (granted it was a $1 test from the dollar store) and it was negative. I took one like 4 days ago and it was negative too. The first day of my last period was Feb. 19- could I be pregnant? Is it something more serious? Am i just being paranoid? Thanks for your time.
