so for a little over a month i have had breast tenderness. and last month(February) when i was supposed to start my period. i only spotted for a couple hours. i thought that was weird so i got a pregnancy test. it came out negative. so i just shrugged it off. well my period is pretty regular i always start within the first 3 days of the month. and now its the 8th of march and at the beginning of this month i also spotted for only a couple hours. could i possibly be pregnant and not know? should i go see a doctor as soon as possible? someone please help me out. if so this would be my first pregnancy. o.O
