1 week overdue and negative test

Hi ladies,

I'll introduce myself first: mom of a daughter and now expecting a 2nd, but everything is different... With the first one, I was 2 months pregnant and didn't pay attention to anything, and now I'm going crazy. I'm 8 days late, have taken 3 tests, and they're all negative. I do have some mild stomach pain, like I'm about to get my period, but I'm not. I've had slight bleeding for the past 2 days, but it's not like a normal period; it's more like old blood. My breasts are a bit more sensitive. Could it be that my tests are lying? ????? Ugh, I'm going crazy. Normally, I'm only max 2 days late!!
