for the past 2 days or so i have had a slight increase in my appetite, normally for example when i would eat a sandwich i would usually only eat like half of it and be FULL! but now i can finish a whole sandwich and eat 3 more with in a hour and a half or so, and when feeling my breast my nipples feel a little more soar than usual? now just to add in a few days ago i had some slight brownish/light red bleeding that only lasted 2 days and my period wasnt till another 12 more days when that happened. my last period was on 9/14 and i had sex while on my period and im guessing my ovulation date was around 9/28 and i had sex days before that and following up to [9/28], ALSO i notice that i get some abdominal pain when i sit down then when i would just laying down or be standing up or walking? im really confused? are these early symptoms or pregnancy? or is this a sign that my period is coming? i need some advice. anything would help!
