For the last 2 weeks everything has been weird. I've experienced very bad headaches for a few days, that bad that i cant been in bright rooms. I have also been experiencing mild cramps, and after sex i am in total pain with cramps, that bad that i don't want to move and i don't even want to have sex. my periods were due on the 27/7/2012 and got my periods 5 days early, i got them about 7pm and were just a small bit of blood for a few hours, then during the night i bled very heavy that it was all over the bed, and thats unusal for me, the day after it was a watery pink colour and wasnt heavy atal it was dribs and drabs here and there untill 7pm the next day i started getting a brownish discharge and then no blood at all? my periods normally last for 4-5 days and im never normally early, my moods have been bad that im finding i have a problem over the simplest of things? has anyone experienced this and should i go to my doctor or is it just normal? im not on birth control or condoms.. could i be pregnant? ive been feeling tierd a lot but i suffer from depression and for me to get tierd is normal but i stopped getting tired, has it come back or does this sound like somthing eles?
