Not sure if preggers

Hi,

I need some advice on this, because what I have been feeling lately I have never felt before.

I have been with my bf for 8 months – which to me is not that long to be getting pregnant……….my period is about every 4 – 5 weeks but this month it is nearly 6 weeks………..last week and the week before I noticed that I went to the toilet alot in the morning……………then I also noticed I had been grumpy with my bf for about 3-4 days on the trot………… I usually am only grumpy a few days b4 my period but only for 1 day………………..I then went on this site and read about the symtoms………….which i kinda related to……….last sat i got a preg test…………but it came back negative……………..but you can’t always be sure……………..then yesterday I noticed that a had a small bit of blood and i kept cheking and by the night time………..there was hardly nothing there……….usually once I noticed a lil bit it starts straight away……….this morning I noticed that there was still nothing but as the day has gone on it is getting a bit heavier, but very different to normal………….

I need some answers………………I am going to the Doctor’s tomorrow but I am still a bit unsure……………I did read that you can still have a period and be pregnant………..what do you think………..maybe I am overreacting because I have worried so much and now I have come on???:S
