I know this is going to sound ridiculous but I used a toilet last week and after I stood back up I realised I had sat directly in something sticky an wet and was due to have my period at the near that time and it hasn't come yet, I have ben feeling quite sick, dizzy and been getting pains for the past few day.

So you think you got some type of urinary infection then ?

In a week there would be no pregnancy signs, and but most likely pains of premenstrual of period coming but not here yet

I don't guess you are thinking you got pregnant sitting on a toilet set ?
