September 17th I had unprotected sex and my cylce started on the 1st of October12& finished on the 7th.

 

On the 10th&11th Of October 2012 I also had unprotected sex.Now my cycle starts on the 7th of every month and last between 5-7 days.Now on this occasion my cycle has decided to come on the 28th of October 2012 and have only lasted 4days.

I am a little concerned because my cycle has always been consistant.

I done a pregnancy test  a week and half ago and the results were negative.

Havent had any cramps and if there is any pain its very minor which also strange.

I had done little research ect, implantation bleeding and its hard to tell the difference between the two but I dont think that this is the case.

This sounds so strangeee! but I am smelling things I wouldnt normally take notice too! I really dont know maybe its my mind playing tricks where its constantly at the back of my mind.

My mum didnt find out she was pregnant until she was 6 months due to having some form of flow every month which is worrying me if this is the same case.

 

If you have any Ideas please share.. thankyou.
