Hi there, can anyone offer any advice - please?!?!?!??!

I have one son who is 3 and when I was ttc him I came off the pill, had one period and then I got pregnant with him - very lucky I know! I have not been on the pill since i had my son.

My last period started on the 12th April 2007 and we decided after this one had finished that we would start trying for another baby. I am unsure about the whole cycle length business etc as I just let mother nature decide but I have not come on yet and I do think im late, Im having crampy type pains in the front and the back and i feel very bloated. i have done tests for a few days but all negative?!?!?!

can anyone tell me if i am late or if its too late im not pregnant or offer me any advice??

thank you so much
