Hi all. I'm hoping someone would be able to shed some light on my situation as I'm very confused. I have a 28 day circle and my period comes like clock work every month. I started my period on 25 JAN 2011. It lasts for 5 days which is normal for me. Then it started again the 22 FEB 2011 but then ended on half of the day on the 23 FEB 2011. The bleeding was normal for me for that 1 and half days but for it to just stop wasn't. After that I just had some very light brown spotting which lasted for another day or 2 and that was it. This month my period is due 21 MARCH 2011 according to calculations but nothing has started yet. My breasts aren't really painful. Maybe around them but I'm assuming its my bra. I did experience very sharp pains right next to my navel on my right side that actually woke me and made me cry out. As soon as I turned on my right it was gone! I got some lover back pain (could be my period) I'm not sure what to make of it. My fiance and I are trying to conceive but I don't know what's going on now with my period after it being normal for years! PLEASE help! Any advice would be much appreciated.
