I am currently 7 days late for my period, I have had 2 negative tests.

My ovulation date was 2nd April but me and partner didn’t have sex on this date, the closest was the 8th and 9th April shortly after my ovulation.

Is it possible I could be pregnant and the hormone is too low to detect in a test because it hasn’t been that long?

I know a friend who had negative tests but blood tests confirmed she was pregnant.

Wonders if anyone has similar situations?

My periods have always been very regular and there isn’t anything changed this month as to why it could be this late?
