6 days late, i have had perios cramps, negative results though?

Hi can anyone shed any light please. I am going slightly crazy!! I am now 6 days late for my period. had period pains to the point of checking and running to the toilet. this will be my 2nd child so not sure if you feel any different to the first? me and my partner have been ttc. My last period was on the 26th march and now 6 days late. i'm never late infact early at times. I'm very bloated and still no positive tests as yet!! with my first i do remember taking tests that came up negative and then few days it was positive so that is keeping me hopeful! does anyone have the same situation and have you then tested positive. Just need that support instead of thinking its all in my head..... thank you ladies xx
