I suspect I am pregnant, but the HPT has dissapointed me before. Where it showed negative 4 times, and I was pregnant, my friend told me that she used the dettol test (urine and dettol) and out of 6 times she had tried she got 2 possitives, and she has two children. Those 2 possitives are now her kids. How accurate can the dettol test be?
