Yes. They do. Usually after 14 day of ovulation menses starts, if a lady is not pregnant. In irregular cycles, ovulation is also irregular and pregnancy test usually requires certain level of Human Chorionic Gonadothrophin hormone to be detected and as such they give false Negative results.(Fertilized ovum takes about 8 days to implant in uterus and then starts to secrete H. C. G. and till then most sensitive test can not become positive.) By the way, irregular cycles lower down the chances of pregnancy and it is NOT a disease but routine preventive check up by your Doctor is good for EVERYBODY.( A stitch in time, saves nine !)
